If you chose to pay your TurboTax fees out of your Federal refund, and if your Federal refund has been delayed unusually long at the IRS (or if it's been reduced), TurboTax will want to be paid. They likely started sending you emailed bills to pay. If you didn't respond by either paying or asking for a deferment, they would ultimately debit your bank account. If you didn't get the emails, check other email accounts and also the spam/junk folders.
See this FAQ that explains the process. The first paragraph has a special phone number if you have a question. You can also use it if you need to appeal a NSF fee (non-sufficient funds/overdraft fee).
Hours are 5AM-9PM Pacific (8AM-12 Midnight Eastern) 7 days.
