I don't shop Costco but the information we were given at the start of the season is that Costco is selling two products side by side.
Turbotax Desktop (Deluxe, Premier or Home & Business). This is to install on your own computer. The box does not have a CD, but it has a code and instructions to download the installer from Turbotax.
Turbotax Live. This is the online version only, including live assistance from a CPA via video chat. The box contains a code you will provide at checkout to show you already paid.
If this is true and if you bought Live Online when you meant to buy desktop, you probably need to return or exchange it at Costco. Like I said, I don't shop there so I can't verify it, but when I read about it, it sounded like a recipe for disaster and confusion.
