After you file

I have two stimulus check that were deposited from two years ago. One 600$ and a 1200$. The bank account was closed. The 600 one was returned but the 1200 dollar one was accepted and not returned. The claim they didn't receive it but I got a deposit date from the IRS. It was June 24 th of 2020. I don't know what to do. No one can tell me.
