Get your taxes done using TurboTax

If one of your dependents was age 17 in 2024 then they are no longer eligible for the Child Tax Credit.  They are only eligible for the Other Dependent credit of $500.

 

If that is not the case the you probably answered a question incorrectly for one of your dependents.  The program shows you when the child tax credit is being used for each child when you complete entry of the dependent.
