Electronic filing - direct debit?

Finishing up on Federal return, but got message that I need to do more before printing.  Turbo Tax Electronic Filing instructions says My Federal return has a balance due and i've elected to pay that amount by Direct Debit.  All bank information was completed.  Also it says I need to mail to IRS a completed form 1040-V with included payment.  Instructions say I need to complete all required steps.  Don't want electronic withdrawal AND mail-in check, but can't get past this point.
