I can't find the cancel option but I think I have filled in something wrong, how can I cancel this return?

(***Note that these steps are irreversible!):
- Login to your account
- At the top, click Tools->Update Account.
- Change your password and email to something else.  Close the dialog when you're done.
- At the top, click Tools->Return Manager.  Click the blue "Create a New Return" button to create a new blank tax return.  This step is necessary because you can't delete the tax return that you're currently editing (The active return).
- Go back to Tools->Return Manager.  Click the Red X that is next to the first return.  This will delete your information and leave only the blank return in your account.
- Logout.

Thank you for using TurboTax.
