Get your taxes done using TurboTax

I purchased TurboTax Premier Desktop download from TurboTax Insider. It launched fine, installed all the updates, allowed me to prepare the return. Seemed legit. However, after February 12 update, the program started crashing on launch.

 

It is not clear if that is due to the genuineness of the TurboTax copy or a bug in TurboTax. This website sold for $40 as opposed to $70 on Amazon. Since we do not always purchase from TurboTax directly but through Amazon, how to know who is genuine or not and whether TurboTax will back up their product from a specific seller or not?
