I gave an incorrect routing number and checking account number for payment within the last hour. How do I change that to the correct numbers?

You cannot change your refund method after you have e-filed or mailed your tax return.

If you need to change your refund method prior to e-filing or mailing your tax return, please visit the File tab on the left side of the TurboTax screen. Navigate to Step 2 to select your refund method which are Direct deposit(this option will allow you to enter or edit your bank account and routing number),Paper check ,Turbo Prepaid Card, and Split my refund between multiple bank accounts or U.S. savings bonds option.

 Note: If you don't see the File tab, scroll to bottom of Home page, click Add a State(you're not actually adding a state, this just gets you into the right menu) and then proceed with the steps above.

If you have already filed your taxes, you won't be able to change your bank info. Please see this TurboTax FAQ, What if I entered the wrong bank account for direct deposit?https://ttlc.intuit.com/replies/3302459
