If you did already e-filed, and your bank account information is
incorrect
then unfortunately you will have to wait to see if you return is
accepted or reject. If rejected, you can follow the steps above and
update the information. If your return is accepted, you would not be
able to change the information. Once accepted if the IRS is unable to deposit
the refund into the bank account provided you would then receive a paper check
in the mail. If your return is accepted, you may be able to try calling the IRS
e-file payment services at 1-888-353-4537 for assistance in updating the
banking information.
