A 2016 return cannot be prepared online, so you'll need to disregard some of the info in the helper's comment above. And you should not have to pay any fees again. And obviously you can't uninstall/reinstall, since you said can't install the 2016 CD software at all.
In regards to opening your existing 2016 tax file, you said "now the CD won't install on my iMac" and that you "have a Mac with the most updated software."
That may be the problem. The 2016 TurboTax program was not designed for current Mac OS X. What happens when you try to install it? Are you getting an error message when you try to install the 2016 CD? Please state explicitly what Mac OS X version you are using.
I don't use a Mac, so I'm going to ask someone who does to comment in this thread later today to see what options you have. Do you only have the *.tax2016 data file and not a 2016 PDF?
@macuser_22 Can you please assist here today? Thanks!
