@Go1Allie - here is what occured:
1) last year you received* the 3rd stimulus which was $1400 per person
2) when you filled out your tax return, the Turbo Tax interview asked you how much you had received for the 3rd stimulus. if you answered 'zero'. then $2800 posted on Line 30. (please look at form 1040 Line 30 to confirm that is what is there)
3) But when the IRS reviewed your return, they know they sent you the $2800 last year, according to their records,
4) so the IRS removed the $2800 you posted on Line 30 of your return, since their records show they already sent it to you. The result is your refund is reduced by $2800
5) please check you bank account records for the receipt of the stimulus last March - May, 2021. if you see it there, then that is why the IRS adjusted your return.
6) if you have no record of receiving the $2800, despite the fact that the IRS records indicate they sent it to you, then you'll need to file a 'tracer' form so that the US TReasury can figure out what happened to the $2800 and resolve the issue.
