Get your taxes done using TurboTax

Now, I can't log onto my loaded 2019 Deluxe version program because an error message reads something to the effect that the key I received in e-mail has been used.  Following is the key I received that worked previously. [product key removed] In many years, I've never encountered this problem before and am beginning to wonder if I should continue using Turbo Tax
