The Child Tax Credit is only for a child who is under the age of 17. When the child is a dependent and age 17 or older they are only eligible for the Other Dependent credit of $500.

@mmwest11 And actually you should have lost the Child Tax Credit last year in 2023 when they turned 17 . Has to be UNDER 17 on Dec 31. Check your 2023 return and see if you got the CTC or just the $500 other dependent credit.
