If you entered the wrong direct deposit account information, you have options to still get your refund:
If you haven't filed yet, you can still change your bank account info for direct deposit.
If the info you provided is for a closed or invalid account, the government will mail you a refund check.
If you entered a valid (but incorrect) account number that doesn't belong to you, there's usually nothing to worry about. Most banks won't deposit tax refunds into accounts where the names don't match. You can try calling the IRS to stop the direct deposit if your return hasn't been posted to their system yet. For security reasons, the IRS can't re-route your refund to a different account, so you’ll get your refund via a paper check
If your return is rejected, you can update your account info along with the issue 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
