If you e-filed:
Banking information for direct deposit is wrong
If you entered incorrect banking information for your refund, you can change it if your return is rejected. If it is accepted, however, it is too late to change it. The bank will reject the refund and send it back to the IRS. Then the IRS will issue a paper check and mail it to the address you put on your tax return. Expect a delay of at least a couple of weeks to receive your refund.
