I wanted to see what TurboTax was like so I made an account. I have no need for it and I would like for my information to be deleted. I started a return but didn't follow through with it.
If
you want to deactivate your account instead, you'll have to send a
message to Customer Service (they'll give you a case number and tell you
what to do next): https://support.turbotax.intuit.com/contact/
