@lauralud36 - it's the Recovery Rebate. Look at Line 30. is there $4200 on that line?
you were eligible for either the 3rd stimulus or the Recovery Rebate Credit, but not both.
THe IRS records indicate you received the 3rd stimulus, so they denied the Recovery Rebate. In effect, the IRS is saying that Line 30 of Form 1040 should be zero.
did you receive the 3rd Stimulus. Check your bank account records from March - May, 2021. If there is a $4200 deposit, then Line 30 should have been zero.
let us know what you find!
