Get your taxes done using TurboTax

I am already paying via direct debit. I provided my bank account info there, but that info does not show up on any of the final tax forms. Line 21a of form 1040 is still X'ed out. Is the direct debit information forwarded to the IRS, or is that payment handled by TurboTax? I'm trying to make sure the IRS has my bank account info on file.
