TurboTax is a dominant (but perpetually flawed) product. Intuit is a terrible company. In the past I've quoted chapter and verse in the tax code where TurboTax has gotten something wrong and for three years it wasn't fixed. I eventually stopped looking.
Other issues, like "seeing" a state form before printing but then that form not actually printing (just missing!) - Intuit didn't even try to fix. They just refunded me my license fee that year as I had to do THAT ONE FORM by hand -- even though within the software it was calculating correctly and was visible right up to the print event.
This license issue is just another instance of Intuit's junior varsity coding and atrocious customer service. Intuit is gaining ground on health insurance companies on my list of least pleasant corporate interactions.
