You cannot change your direct deposit information after your return has been accepted. The IRS does not allow it. If the refund goes to a closed or wrong account, then it gets sent back to the IRS and then the IRS issues a paper check and mails it to you. If you use refund processing and the third party bank is involved, then it goes into a mess that can take months for you to get your refund.
You need to be very sure at the time that you file your tax return that you are entering correct banking information. Check it and double check it before you e-file.
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.
