TT "Clear and start over" feature

[PipiR]

I seem to have an Intuit and a Turbo Tax account. Each one has a different user name.  I understand that I can only delete the information in the account, but not the account itself. How do I delete the information in my Turbo Tax account? In this forum they talk about the "clear and start over" feature, but that seems to refer to the tax data itself, not the account.
