I filed my 2021 taxes and stated that I did not receive my 3rd stimulus when I actually did receive it in March of 2021. What do I need to do?

How can I amend my 2021 taxes that I electronically filed on Jan. 27, 2022?

The IRS will probably adjust your return based on their records so don’t do anything until your return is processed and your tax liability has been settled.

If the amount on the tax return is not correct, the IRS will make the corrections and send you a letter with the adjustment.  You do not have to amend your return, but if the adjustments results in a tax due, you will have to make payment before April 18th.
