Answer: They're all over the place. You find them as you'd find any other opportunity, via networking and job listings. There's also an added opportunity if you already have a job, in that you might be able to convince your boss to let you work from home.
To demonstrate, here are 17 current work from home job opportunities for people in all kinds of fields. If these are the kinds of things you're looking for, great! If not, use them for inspiration. They're just the tip of the iceberg.
Obviously this is a specialized position that requires specific education, experience, and a state license (a Florida bar admission, in this case). The posted salary is between $38 and $43 an hour, and they want someone willing to work part-time, remotely, for about 20 to 25 hours per week. The job lasts between two and three months, "with a strong probability of an extension."
This one sounds interesting and even fun for the right person. Duties include "develop[ing] curricula and writ[ing] conceptual quizzes that introduce quantitative industry fields to aspiring scientists."

It's a 20-hour-a-week job that pays $40 an hour.
The tutoring industry is pretty hot for work-from-home jobs that don't require a specialized certification. This position, for a company specializing in language tutoring for Chinese clients, only requires English fluency and the legal right to work in the U.S. or Canada. Take note of the pay and hours, though: $18 per hour, for work between 5 a.m. and 9 a.m. Eastern time.
For this job, you need to be a licensed RN, and there's a strong preference for people who are bilingual in English and Spanish. The job is with HCS Healthcare, "managing inbound calls to provide quality triage assessments and care advice," and the pay starts at $30 an hour.
This is a true, entry-level position paying $13-an-hour. The main restriction is that while it's a work from home job, they're limiting applicants to people who live in Illinois or Indiana.

Listed at FlexProfessionals, this job pays between $25 and $30 an hour. It's for someone with five years of accounting/bookkeeping experience, and involves "maintaining [a] portfolio of client account books.

Another language tutoring job--but this one, for Transparent Language, requires that you be bilingual in English and one of 31 foreign languages (everything from Chinese to Urdu). The job pays between $12 and $20 an hour, and the listing says you can work from anywhere, as long as you have a "fast, reliable internet connection."
This is via Robert Half Technology, which says it has a client in Ontario, California looking for a Systems Engineer II. The salary is $45 to $50 an hour, working remotely. Obviously it's a specialized position with too many requirements to list here.
Again, obviously a job with a lot of prerequisites--as it should be. This is for a licensed clinical social worker (or other mental health professional) with at least a master's degree, and it's a part-time job providing "telecounseling services to clients in an on-line intensive outpatient/outpatient substance use disorder treatment program." Pay is $40 an hour.
11. Design Engineer
If you happen to be a Maryland-based design engineer with "deep knowledge/experience with Visio, Excel, PowerPoint, Word, and Google Docs," this is a possibility for you. Kelly Services has the opportunity, which pays $29 an hour.
For this one you should know how to code, and be interested to learn to teach others to code. You will "work directly with Flatiron School students, acting as on-demand instructors while students are working through the curriculum." It's a remote job (as these all are), paying $20 per hour.
This sounds like an interesting job for the right person (who will have at least a BA in psychology and at least six months experience as a coach, counselor or therapist). This company, Ginger.io, provides mental health support "exclusively over text chat, which is why coaches must have excellent writing skills and the ability to convey warmth through this medium." The pay starts at $18 per hour.
This isn't the job for everyone; people who haven't transcribed before tend to underestimate how long it takes. That said, Transcribe Me! has jobs for transcribers paying $65 per audio hour, which might work out to about $16.25 an hour. Separately, National Capitol Contracting has transcription jobs paying $40 per audio hour.
For this remote job, you'll have to be an "expert in curriculum theories and practice, with experience in the design and implementation of strategies to improve learning and teaching outcomes." The position is with Elevate K-12, and the pay works out to $15 an hour.
We'll wrap this up with a work-from-home customer service position from the company that owns Enterprise Rental Cars. Pay works out to $12.85 an hour, but there's also the potential for monthly bonuses around $600. You do have to be willing to work weekends.
