If you already paid, it is probably too late, but you can try talking to customer support. To use an affiliate discount you are supposed to go into the software via the affiliate site.
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.”
