If you need to change your direct deposit information please see this TurboTax FAQ: https://ttlc.intuit.com/community/accessing/help/how-do-i-change-my-transferred-direct-deposit-infor...

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

You can review the direct deposit account information you entered by looking on your printed return. This will be found on your 1040 under the Refund section. 

Now, if your recently-filed return is in pending status, wait to see if it is 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 and correct the information.
• If accepted, you'll get your refund check in the mail or will be direct deposited if you listed a valid bank account when you filed.
