If I entered the wrong amount for my 3rd stimulus check do I need to amend my return?

No do not amend.   You just have to wait for the IRS to fix your mistake.   By answering incorrectly about the stimulus amount you received you put an amount on line 30 of your Form 1040.   The IRS checks that line.  They know how much they sent to you.   They will reduce your refund by that amount.   This will delay your refund so expect a wait.

You probably do not have to amend your return. The IRS will catch the error and correct it. Wait until you see what the IRS does. Do not file an amended return until the IRS has finished processing your tax return and you have received your refund.

Correcting the error will delay your refund.
