I want to delete my tax return although I have paid for it. How can I do that?
If you are walking away you can change your SSN to a phony SSN.
First call support to ask for a refund.

If you've already paid, you can Contact TurboTax Support to request a refund. Choose the 'Billing' option from the phone menu.
Also, you can start over if you want and still Efile. Here's How to Clear and Start Over.
