State tax filing

I followed these instructions but I don't think the form is calculating correctly. To my understanding, the deduction should be capped at 2500 per dependent per adult. The issue is the system only ask for one number (not by parent or dependent), then appears to deduct the whole value. It does not appear to cap it at the 2500 limit. Keep in mind that the contributions beyond that could be rolled over. 

 

I contacted customer service but they barely seem to understand the issue. Anyone know of how to enter it considering my contributions go past the limit and I'd like to carry the additional over?
