2,800 could be for the 3rd Stimulus payment. Do you have an amount on 1040 line 30 for the Recovery rebate credit? Did you not get the 3rd Stimulus payment? Or qualify for more? Line 30 is only if you didn't get the full amount or qualify for more.
If the IRS thinks they sent it to you but you didn't get it request a trace for a missing third Stimulus payment
