You will need to phone TurboTax Support for any billing issues.
Hours are 5AM-5PM Pacific (8AM-8PM) Mon-Fri, but they are open tomorrow (Sunday) as well, due to the filing deadline. Here's how to get a phone number or schedule a callback, but it won't provide a number when they are closed.
When it asks for your issue, just type billing issue without quotes. If you use the term "refund", it may give you info on tax refunds.
