Unfortunately, once you have upgraded or added features to your TurboTax return, there is no way to downgrade or remove the extra features. You would need to create a new return to use another product.
To start a new return, select “Start a New Return” from under “My Returns” in the top left corner. When you make a new return, don't choose a return from the list to transfer, instead pick "Create A Different Return".
Once you have started your new return, you can select “View All Returns” from under “My Accounts & Returns”. Then delete the unwanted return by clicking the small Trash Can next to it or “Delete” under the return’s name.
