If you already filed your tax return they are not going to give you a refund for choosing a software version that you already used. But you can have that discussion with customer support.
No one in the user forum can resolve a billing issue. If you have a question about your TurboTax fees or billing, make sure you use the word “billing” in your request for help. Do not use the word “refund.”
