Why is only one dependent showing up on my state return

The dependent child must attend a Louisiana school or home school (kindergarten through 12th grade) at least part of the year.  Does the dependent meet those qualifications?

Louisiana Department of Revenue School Expense Deduction may be found here.

Yes, both dependants went to a Louisiana school.

In your other post , I noted that if a dependent was 3 years of age or younger, that the dependent's name would not appear on that screen. Is it possible that one of your dependents was 3 years or younger?

I believe that is the issue. Thanks for clarifying.
