If this is a USA return, I assume you are referring to TurboTax Live. Are you trying to choose regular Free Edition, Deluxe, Premium? If so, here's how to remove the Live feature and select a different edition. If it started you in Live, you can use the "Clear and start over" method shown in a link at this FAQ:

If instead, you happen to be asking about a Canadian product, then you are in the wrong community forum. You would need to go to the Canada TurboTax website.
