Turbotax does not let me enter dependent care credit info for 13 year old child

My son turned 13 in Dec 2022.  When I tried to enter dependent care credit, I got error message in Turbotax:

Your child is Over Age 12 and was not disabled, his expenses will not qualify for the child and dependent care credit.

 

How come? Dependent care flexible spending account covers child up to 13 years old. Why turbotax says 12?
