If you have not already
filed: TurboTax will ask you for your direct deposit information

If you have already filed:
Once
your return has been accepted (or mailed), it's too late to change your bank
account for direct deposit. If the info you provided is for a closed or invalid
account, the government will just mail you a refund check.
If the info 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. You can contact your
bank and alert them that you have made an error in the account number.
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
(look for line 76).
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.
