Can you please provide more information about your problem? What is the exact error message that you are getting? Are you using TurboTax CD/Download or TurboTax Online?
I have entered the licence code at least 6 times for accuracy….Getting: All available activations for that code have been used. Error Code: 603. We have not yet filed one return of the 8 we paid for with the Deluxe Online Edition. It is frustrating to navigate the solution pathway to this problem….
