Get your taxes done using TurboTax
I don't work for TurboTax, but if that happened to me this is what I would do. TurboTax has a 100% satisfaction guarantee for the desktop product (such as your download from Sam's) regardless of whether it was purchased directly from TurboTax or from an authorized retailer (of which Sam's is one.) That policy allows one to ask for an unconditional refund within the first 60 days. There is an online form to ask for the refund at the FAQ below. There is a place in the form to describe your issue and to attach a file containing an image of your receipt. Once you are sure you are getting the refund (not sure how long it takes), you can then buy the correct product.
FAQ: How do I request a refund for my TurboTax product?
I believe it gives you a case number. The FAQ also has a link to "Track my request" if you need to check on it later.
