I have already received my federal refund and paid my state taxes. I’m supposed to receive my $1,800 Recovery Rebate Credit, but I haven’t yet. What do I do?

My $1,800 is on my line 30 on my tax documents.

That amount is already factored into the calculation of the refund listed on Line 35a.  Did you receive the amount shown on Line 35a?

2020 Form 1040 (irs.gov)

If not, the IRS may be reviewing your eligibility for the Recovery Rebate, or its record may show that you already got the stimulus payments.

Yes I did. But how did they come up with the $4,108 then??
