What to do with my tax return?

First off, I am a 20m college student who recently got a large tax return for someone my age. I have a Roth IRA started and I will put some of the money into that already. I also do not have any debt.

I want some insight on my options here.

1. I invest all of my tax return into my Roth IRA

2. I invest half into my Roth IRA and the other half I choose some growth stocks I like (JPM, GOOG, HD) that I would hold for awhile. Maybe I would add an ETF like VT in there too.

I guess you could say I have FOMO but I would appreciate some insight during this time when there are a lot of stocks on sale. What would you do?

Thanks for replies
