I will add, and I don't mean to insult at all, if you're asking this question, there's a lot of reading and learning you should do first (as there's just basic terminology you don't know yet, like what a Roth IRA even is).
We all started in the same place you are now, and learning a little more (some basics) before you dive in is crucial. :)
I second the recommendation to JLCollins' stock series.
