That is one of the list of generic reasons they give if they changed the Recovery rebate credit on line 30. How much is on 1040 line 30?
Did you receive the full amount for both the first 2 Stimulus payments? Better check your 1040 line 30 and see if an amount is listed. That's been a problem. A common adjustment is if you claimed the Recovery rebate credit on 1040 line 30 when you already got the Stimulus payments or got the second one after you filed. Or you might have answered the Stimulus questions wrong and tried to claim it again or some more on line 30. So the IRS took it off because you already got it. They know they sent it to you.
