Try Googling Turbotax Sowftare Download. I couldn't find it from my account either. I have no idea how to get to it from the usual account sign in.
The problem is, I found it, downloaded and installed it but now I can't activate it because there is no way to pay for the version I have. Been looking for how to buy the code for a while now. Trying to get TT up and running is harder than the actual work of doing the taxes.
