You used TurboTax software to prepare your taxes. You owe TurboTax for the software. Not paying what you owe makes you a deadbeat, just as if you ordered a meal, ate it, and walked out without paying. The fact that you opted to pay with your refund and that the IRS has not processed your refund does not mean that the service that you used became free or that it is fraud to request you to pay the bill that you owe.
