Start an onlyfans maybe.. jk lol. There's Fiverr if you have any good skills you'd like to share with others. Never tried it before, but I know you can sell art commissions, audio/music, graphic designs etc. If you don't have that type of skill, then there's also Rev transcriptions. I've given it a try before. Basically, you just listen to audio files and type out what the people are saying. Imagine subtitles pretty much. I don't recommend it though since the pay rate is super low, and it's more like pocket money than anything.
If you're looking for something more of an actual job with a company, there's handful of work-from-home jobs out there. Mostly for sales reps positions though from what I've seen. Stuff like answering phone calls and providing technical support from your home I would guess.
