The program used to require you to enter the routing and account numbers twice in the blind (where you don't see what you entered already and you cannot "cut & past" the prior info) but sadly they stopped that safety feature. In the future I highly recommend you "sleep on it" before filing and come back later to review your return again before filing and/or have another human check your DD entries before you file ... remember you are acting as your own preparer and the program cannot possibly know that you made a data entry error in these fields.
Good thing my professional tax program still requires it to catch my "fat finger/dyslexic" data entry errors.
