If you have an active ADVANTAGE account you DID authorize the charge ... it is your responsibility to cancel the account ... you should have gotten a reminder email recently letting you know this was going to happen.

3. Select Remove product under each product listed
4. Once all products have been removed, you'll see the Sign up now button. This means your subscription has been canceled.

Tip: If you missed the cancelation deadline for this year's TurboTax product, simply wait until you receive your CD or download, then submit an online refund request within 60 days of receiving your product.
