How old is your dependent?   If they are under 19 you don’t need to check that.   It’s only for ages 19-24.

If your child is between 19 and 23, you can find this question in the My Info section. Navigate to My Info on the left of your screen, Your household, select your child's name to expand, then choose "Revisit" to go through the interview questions. 

If your child is under 19, the box should not be checked, because they automatically meet the age test for a qualifying child.
