TurboTax charged my credit card two months in a row. $70.00 has hit my credit card bill for two months in a row. how do I get credit back for one of the charges.

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.”
