As soon as you entered your children Turbo Tax gave you the full amount for the Child Tax Credit. So your refund would look too high. Then later you enter how much Advance you already got so it is subtracted. Check line 28. Line 28 is not the advance you already got but just the remaining amount. The total credit or the advance does not show up on your tax return.
Oh and your total refund isn't necessarily the amount of the credit. It either adds to your refund or reduces a tax due.
