Turbo Tax not recognizing a dependent

My child is 21 and earned over $4400.
However, my child:

 a) was a full time student all of 2022

 b)  did not provide over half support


I see here on Turbo Tax tips that,

How much can a dependent child earn in 2022?

A qualifying child can earn an unlimited amount of money and still be claimed as a dependent, so long as the child doesn’t also provide more than half of his or her own support.

 

All of the above is true for my child.

Why isn't Turbo Tax recognizing my child as a dependent?
