We bought Turbo Tax Deluxe from Sam's Club, where do we go to get the software?

Let me start by saying the website is such a mess and so difficult to navigate.  wow..

 

Anyhow

 

We bought TurboTax Deluxe from Sam's Club and I need to get the software.  There is no activation code, nothing.  it is on our receipt and I have the piece of merchandise you take to pay for it but nothing there tells you how to get the software. 

 

What do I need to do?  This is crazy...  We don't want to have to pay for a second copy.  Please help
