Same issue.
finissed taxes on TT using a 5 year old mac. When I bought state e file TT shut down and will not open either my saved return or TT 2019. Bought at costco loaded disk.
Spoke with rep no solution.
said need to down load 2019. did that. then went to have 2018 import information. won't do it.
So have to do taxes over and enter in all information even though I have been using turbo tax on this mac for the last 5 years.
Even if this is not a TT software issue how about warning if using an older mac possibility it will completely fail after you have completed your taxes, ran checks but does not let you file. Really sucks.
