I'm having a similar issue with my 2014 TurboTax Home & Business except that I am able to open the program on my iMac ((macOS Mojave 10.14.6 (18G8022)) and have added a lot of information to the file. I few days ago, after a few minutes of entering information and scrolling down, the program "hangs" according to the report that gets issues.
I've read several posts on this forum and learned that, even though the issue according to Intuit was caused by a javascript change that Apple made, TurboTax issued a fix (a script) that but that the fix has been removed because TurboTax doesn't support versions older that three years. I am appalled that such support disappears after only three years. I suspect that many users need to go back further than three years and either use the version they bought to do their original taxes or to amend a return.
I have been using TT for at least twenty years.
I am desperate to get my 2014 TT fixed so it works. Help!
