Warning: this advice won't solve your problem. You can go to Apple Support pages but you'll need to 1. backup your entire hard drive, 2. download and install a previous OS version (see Apple Support), 3. re-install TurboTax 2014 or 15, 4. do what you need to do, 5. reinstall current OS, 6. restore backup.
I've been a Quicken/TurboTax for Mac customer for over 20 years, and each year, I say this is the last. I'm so fed up with Intuit's poor support for Mac OS AND its HORRID customer support.
