Did you enter the advance amount you did get? Then the rest should be on line 28 if you qualify like if your income isn't over the max. Oh and your total refund isn't necessarily the amount of the credit. It either adds to your refund or reduces a tax due.
Turbo Tax started out giving you the full amount as soon as you entered your children. So your refund was too high. Then later you enter what you already received so it subtracts out what you already got. Check 1040 line 28. That is the remaining credit you get, not the advance you already got. It either adds to your refund or reduces a tax due.
I found this in a news article, it explains it pretty well........
While the CTC expansion was structured to not increase taxes on any household, a dollar of credit received in advance results in a dollar less received at filing time. For families unaware of the trade-off, it could mean a surprise when they see their refund total this year.
Consider a married couple with a 10-year-old child who normally received their $2,000 CTC when they filed their taxes. They would have received $1,500 of their $3,000 in advance. As such, they could potentially see their refund shrink by $500 even though their total benefit increased to $3,000 because they are left with $1,500 instead of their normal $2,000 at tax time.
