I recieved a letter from the IRS, 3 hours after filing my 2021 taxes, stating they paid me $13.90 in interest. Do I need to ammend my return? If so, how do I ammend it?

The IRS accepted my return an hour after filing so it is already in their system. Is there a threshold of what needs to be claimed for interest? Also, I claimed a 1099 INT on other interest so does that amount play into a potentional threshold? Guess I should've gone to the mailbox before doing taxes!
