Direct Deposit

I e-filed my return with Turbotax and selected the option the due tax to be withdrawn from my account on 4/18. This hasn't been done yet and when I print out my files from Turbotax there is no information for the direct deposit. Should I go and send a check as well although it's already past due now. is a delay in withdrawal expected? I am really hesitant to do this via Turbotax in future :(
