I got the same problem and called support.
Try install and uninstall and end up with a turboxtax without the state part because getting 42016 error (unable to update).
Because my state software is missing, I can't even open the file and print the return.
well, luckily I have mac around, so I asked the support team member to give me a mac key for the same TurboTax version .
After install TurboTax on macbook and transfer the file over to Mac. I am able to complete the e-File in 3 minutes
