I think I gave the wrong information regarding my direct deposit

[MichelleLO]

If you have already e-filed or mailed in your return, you are not able to make any changes to your bank account information. If your financial institution rejects the deposit, the government will mail your refund check. 
Please see the FAQ: What if I entered the wrong bank account for direct deposit? for additional information.
