If you haven't e-filed your return yet (or your return is in Rejected status), you can revisit the File section in TurboTax to either correct your account information or choose a different tax payment method.
For a return in Pending status, you'll need to wait for its status to change to Rejected or Accepted.
Once your e-filed return has been accepted, it's too late to update your bank account or change your payment method in TurboTax. Instead, call the IRS e-file Payment Services right away at 1-888-353-4537 (They're open 24/7).
You may be penalized if your tax payment isn't received by the filing deadline, so don't delay.
For problems with state tax payments, contact your state tax agency.
