@BeaverDamn - Here is the problem
When you completed your return originally, you entered that you received $1500 in the advance child tax payments. That is why I asked what is on line 14f. Since you entered $1500 and now state it was really $3000, that explains the $1500 the adjustment the IRS made. I find that most filing joint make the same mistake: you received Letter 6419 from the IRS stating how much you received, but THERE WERE TWO LETTERS, one addressed to each spouse. When TT asked how much YOU received in advance, you needed to ADD BOTH LETTERS TOGETHER. I suspect that is why you originally entered $1500 and not $3000- the 2nd letter.
2) your benefit is limited to $4000 ($2000 per child) due to your income. So originally, you had a $4000 benefit less the $1500 you stated you had already received, so Line 28 was the remaining $2500.
3) but now we know: You had a $4000 benefit less the $3000 you had already received, so Line 28 should have been $1000, which is $1500 less that it was upon submission, leading to a $1500 reduction in refund / increase in what you owe.
make sense?
