How does one find *legitimate* work from home jobs?

I am trying to look for a work from home job. My current job has been laying people off and has reduced me to part time. I am seeing a ton of work from home jobs on Indeed but how can I tell if they are legitimate? What red flags should I be looking for? I've been watching a lot of Kitgoba so I think everything is a scam.

I am not wanting my dream job. I'd be happy with $30k a year and health insurance.
