@Toots6969 - if you have the documentation, how bout explaining it on this board?
I suspect the issue has to do with Line 30 or Line 28 of Form 1040.
if you did not enter the money you had already received for the 3rd stimulus. Line 30 is wrong and the IRS corrected it.
if you did not enter the money you received for any children from July - Dec, 2021, Line 28 is wrong and the IRS corrected it.
