E-version of 2019 turbo tax won't load on MacBook Air

There is no such thing as an "E-version" of TurboTax. If you have the CD/download version you need to drag the dmg file to your applications folder to install it.

2019 Premier CD will not load onto my Macbook Air.  Error message says it may be an incorrect version of OS X whatever that means.
