It may be difficult to get a product refund, since paying allows one to get a PDF of the completed return or print a copy for filing. But nothing account-specific is handled in this user forum. You'd need to discuss it with TurboTax Support to see if you can work out anything. Here's how to reach them during business hours. If the system asks how to triage your issue, just say "billing issue".
Support hours are 5AM-5PM Pacific, Mon-Fri this time of year.
