I once had money sitting in an IRA for about a year before officially investing it, so I feel you! I just did not understand the process, so I just let it sit there.

I would start here if I were you. JL Collins has some great stuff on investing. The Money Guy Show on YouTube is also another great source for free investing content.

Generally with IRAs, since the money cannot normally be touched until 59 1/2 years old without penalties, a lot of people invest in low-cost index funds in these long term investing accounts.

Good luck!
