Paid for the Optimizer Feature but it didnt activate and I never used it. I dont want to pay $20 for it on my final bill.

Unfortunately, there is no way to downgrade a TurboTax return. You would need to create a new return to go down to a lower 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.
