After you file

@gregorybutlervg3 WAIT - if you are stating that your tax refund was adjusted by $4200 that is likely the Recovery Rebate Credit and not the Child Tax Credit. 

 

Here is what most likely occured. I've seen a lot of posts like this with the same result.

 

1) for the stimulus, you were eligible for $1400 times the number of people in your family or $8400

2) during the Turbo Tax interview you were asked to enter how much you received and were also prompted to look at Letter 6475.  I suspect you have that letter and it states $4200.  BUT THERE WERE TWO LETTERS. One for each spouse and each letter noted $4200, which were to be added together!!!!!

3) So I suspect you entered $4200 as the amount received

4) the result was $8400 less the $4200 entered meant $4200 was posted on Line 30.

5) But the IRS records are that they sent you $8400, so they adjusted Line 30 to zero which reduced your refund by the same $4200

6) please check you bank account statement from last March - May, 2021 and confirm you received $8400.  If yes, then the IRS adjustment is correct. 

 

does this make sense?
