If you've already filed and your return has been accepted or mailed, it's too late to change your bank account information for direct deposit . If the info you provided is for a closed or invalid account, your bank will return the refund to the IRS and the IRS will mail a refund check to the address provided in the return.
If you haven't filed yet, follow these steps to change banking details:
1. Sign in to your Turbo Tax account and click 'take me to my return'.
2. Click on the 'File' section.
