After you file
It depends.
No, if you entered the wrong amount but the Recovery Rebate Credit is being calculated on your tax return, you do not need to do anything.
Correcting Recovery Rebate Credits on returns already filed
However, if you entered the wrong amount and the Recovery Rebate Credit was not calculated on your tax return, you would need to file an amended return if you determine you were entitled to the credit.
You will need to look at your Form 1040 to determine if the Recovery Rebate Credit was already included in your return. If you claimed the rebate recovery credit, it will show up on Page 2, line 30 of your Form 1040 as the Recovery rebate credit. See the sample form below.
See the link below for instructions on how to print your return after filing to help you determine if you claimed the credit or not.
