There is no fee to amend a tax return unless the change you are making requires an upgrade to a more expensive version of the software, so it is not clear why you had to pay more when you amended. We cannot see any of your information.
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.”
