Had the same issue on my MacBook Pro, running Mojave 10.14.6. TurboTax Home and Business kept hanging on extracting the update. Turned off my AVAST antivirus scans for files opened on the machine. Bingo. Extraction worked like it should. Updated, relaunched and works fine. Turned my AV software file scan back on.
Should not have to do that in order to install this software from a company like Intuit. They need to fix this issue.
Suspect others having similar problems will also find this is due to their AntiVirus software as well.
