Direct Debit is only for Efiled returns, so you wouldn't see anything on the actual tax form itself for direct  debit...is that what youre stating?  

If you look at a federal 1040, you wouldn't see anything on it for direct debit either.

Double check the routing and account numbers that were entered, have the client contact their bank, was a debit attempted at all?  If the info you entered was correct but UT just didnt do what they were told to do, Im not sure what more you could have done.

I try and get my clients to make their debit dates a week prior to the due date, ,just in case it doesnt happen for whatever reason, theyve still got a few days to get payment made in time, if they want to wait for the very last day, they can go online and make it themselves.
