I think I put the wrong bank routing information down,how can I change it

[AnnS7]

If your return has already been accepted, and the bank information you provided is for a closed or invalid account, the government will mail you a refund check. Once your return has been accepted (or mailed), it's too late to change your bank account information or your refund method.

If the info you entered is someone else's account, don't worry – some banks won't deposit tax refunds into accounts where names don't match up.  The best way for you to track your federal refund is to call the IRS at 1-800-829-1040.

If your recently-filed return is in  pending  status, wait until it's either accepted or rejected.

• If rejected, you can update your account and any issues that caused the rejection.   Open your return in TurboTax and go through the File section again to update your bank account before re-submitting your return.
• If accepted, you'll get your refund check in the mail.
