You would have to contact the vendor for this. I can't imagine they wouldn't exchange it. Insist that they provide a shipping label for a free return. I find it surprising that they would even sell Turbo Tax Deluxe 2016. Were the product properly designed, it would have a couple of "shims" that enable it to be updated year by year as the forms are changed one iota at a time. The very notion that they sell a 2016 version that is separate and distinct from the 2015 version leads one to conclude that it is, shall we say, shady. But that is strictly IMHO.
