Get your taxes done using TurboTax

You have to enter your bank information separately in the Federal section, then again in the state section...because:
1)  Some people may not use the same back account for both Fed and state
2)  And some people will use a credit card to pay one, and a bank account for the other.
3)  AND some states don't allow you to arrange to pay at all when you efile...and you have to pay the state separately yourself, either by check, on the state's own payment website.

IF you haven't filed your state, look for your payment options during the filing process.

IF you have filed your state already, save a new PDF file of your tax return, and then look at the state copy of the "Electronic Filing Instructions" at the start of the state PDF section.  That will show you what you actually entered for your payment to the state (IF..IF it was possible to do so).  IF you did arrange a DirectDebit...then the Bank account routing number, account number, and debit date will show on that Instructions form
