FAQ: What is the TurboTax phone number?

Or could it be the following scenario?
Did you originally choose to pay your TurboTax fees out of your Federal refund, and if so, was the refund either delayed a long time at the IRS, or did the IRS reduce your refund to the point where it no longer covered the fees? In either of those 2 scenarios, TurboTax would want to be paid. They start by sending emails with a bill to pay the fees. If not paid, then they email you that they will debit your bank account if not paid. If still not paid, then they send an email saying the debit will occur. If arrangements are not made immediately at that point to either pay or request a deferment, then they perform the debit.
