Yes it said you were over 150,000 so it gave you a reduced amount of $1,960 instead of 2800. It only phases out between 150,000 and 160,000 before it stops. But you answered you didn't get any of the 3rd Stimulus payment so you tried to claim the Recovery Rebate Credit. BUT the IRS records show they already sent it to you.
2,800 is the 3rd Stimulus payment. It was 1400 for each person. Did you already get the Stimulus payment they sent out last year starting March 2021? Did you get IRS letter 6475 saying what they sent you? If you are married you should each get letter 6475 for half.
Double check your bank statements and check your IRS account to see what they sent you. Check both IRS accounts if married.
