I bought the 2016 version and had it downloaded (no CD drive in my comp).
However, I realize now that I have to use the online version. My machine is on Linux.
I did the same thing last year and I think that I was able to use the online version and at the end TurboTax recognized I had bought it.
I don't believe I was charged last year. If I did, I wasn't aware I paid twice 😮
