We cannot see your tax return so we cannot explain the amount of your CTC. Did a child turn 17? You lose the CTC when they turn 17 and you get the $500 credit for other dependents instead.
If you do not list all the dependents on your W-4 then more tax will be withheld from your paychecks resulting a bigger refund (or less tax owed).
