Will the deduct the portion of ctc you've already received from your tax refund?

Sort of.  You will only get the remaining amount on 1040 line 28.   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.

Before filing,  You can preview the 1040 or print the whole return

@VolvoGirl is correct. Any amount not received shows on line 28 of your 1040.
