Once your return is efiled and accepted, you can't change your method of payment. It is also not possible to file an extension if your return has been efiled and accepted because is is already being processed by the IRS. If you entered your bank information for direct debit to pay your tax debt and the information was wrong, please call IRS e-file Payment Services at 1-888-353-4537 right away or use IRS website
www.irs.gov/payment to make alternate payment or contact your state tax agency, as appropriate.See links below that provides more information.
