child tax credit for 17 year old

One of our daughters turned 17 in Dec. 2019.  TurboTax wants to give us the child tax credit which was rejected when I went to file (turbo tax said we qualified).  I was just going to delete her under our family section under dependents but I believe we can get a smaller credit for other dependents?  But I can't figure out how to do it? Turbo Tax just keeps saying we qualify for the child tax credit
