I bought a second TurboTax Premier license key but can't download free state

I bought a second copy of TurboTax Premier for $82.99 from Amazon and it includes one free state download.  I did that instead of paying $45 for a state download because I also wanted an additional 5 free federal e-files.

When I try to download my one free state, TurboTax wants to charge me $45 as though I've already used my free state download.

I confirmed that I am using the newly purchased license key, not the original one.

How do I get my free state download?
