@RedDotTer Those are generic reasons why they adjusted the Recovery Rebate Credit on your return. A common adjustment is if you claimed the Recovery Rebate Credit on 1040 line 30 when you already got the 3rd Stimulus payment or reported the wrong amounts. The IRS knows they already sent it to you. Line 30 is only if you didn't get the full amount or qualify more.
Did you get the 2,800 back in March - May 2021? If you didn't get the 3rd Stimulus check but the IRS shows they sent it to you then request a trace for a missing third Stimulus payment
