I am a stay st home mom looking to supplement our income. But I can't find any legitimate jobs that don't require huge amounts of $ upfront or are some sort of scam. Can anyone help me??

You are right, it doesn't come easy to find work from home but one thing you might try seeing as you are on the computer is invest in an ad to do script for exams, university students, high school students, companies needing research done, and there are many ways to do that just sitting at your computer, maybe going to the library and rsearching, etc.
