Have you been able to update the program? Quit Turbo Tax then relaunch it. I would even turn off your Mac and reboot it after you quit Turbo Tax. Have you tried reinstalling Home & Business?
Since you now have to log into an Intuit Account all your downloads and licenses are listed there (even if you bought it from somewhere else) so if you need to download to install it again or install on another computer, even on the other operating system (Windows, Mac). And the download will always be up to date with all the updates.
