Did i make a mistake

[Monlee]

I think I made a mistake after filing my taxes.  Long story short, I downloaded and made an account with Robonhood on December 8th, I received a free stock worth a little less than 5 dollars.  The price of it has gone up and down, but I believe at the end of the year it was worth a little over 5 dollars.  I never sold it or have done anything else related to stocks so it's the only one I own.  By the time I filed my taxes I had forgotten I even had it.  My taxes were accepted and approved by both Ohio and the IRS.  I already got my Ohio refund, and am currently waiting for my federal refund, DDD of 2/26/2020.  I just remembered I had it and am worried the IRS is going to do an audit or whatever they do.  This is only my second year filing so I really have no idea what I'm doing or if I even needed to report it.  Any help would be much appreciated.  Now I'm worried I won't get my federal refund now.  Sorry if this is a stupid question, like I said when it comes to taxes, I'm a compete moron.

If you didn't sell the stock you don't have to report it on your tax return.
