Once your return has been accepted (or mailed), it's too late to change your bank account for direct deposit.
If the information you provided is for a closed or invalid account, the government will just mail you a refund check.
And if the information you entered happens to be someone else's account, don't worry – banks won't deposit tax refunds into accounts where the names don't match up.
Now, if your recently-filed return is in pending status, wait until it's either accepted or rejected.
- If rejected, simply open your return in TurboTax and go through the File section again to update your bank account before re-submitting your return (don't forget to also take care of whatever problem caused the rejection).
- If accepted, you'll get your refund check in the mail.
