Can I delete my information and not file my taxes

Once a TurboTax account is created, it cannot be deleted.  You can simply abandon it.

If you'd like to clear any data that you may have entered into the program, you can use the "Clear and Start Over" feature (see below).  

You can remove or change information in your TurboTax account by clicking Intuit Account at the top of the online program screen after signing onto the account.  Click on Account Settings.  Edit any information in both Profile and Security.

To deactivate an account you will need to contact TurboTax support for the procedure.
