If you have not filed, you can change your refund method by signing in and go back into your return then, go into the File section again to choose a different method.

Once you have filed, you cannot change your refund method; you will ultimately get a paper check. For example, if the direct deposit information is wrong, what will happen is basically the IRS will try to deposit
the refund into the account on record. Since the information is not
exactly correct, the bank will reject it and send the refund back to the
IRS. Once the IRS gets your refund back they will issue you a paper check and send it to the address that you put on your return. You can call the IRS directly at 800-829-1040, M - F, 7 a.m. - 7 p.m.
