Am I forced to pay since I accidently upgraded to turbotax delux and didn't use any of it's features? Now trying to get back to turbotax free but can't figure it out

There is no way to downgrade a TurboTax return. You would need to create a new return to go back to the original product. 

To start a new return, select “Start a New Return” from under “My Returns” in the top left corner. 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.
