Then for instruction 4, In Finder, select the Go menu at top and then select Go to Folder....
Type ~/Library/Application Support/ Turbo Tax 20xx and select Go. Select the TurboTax * 20xx directory if it appears and delete AuthorizationClientContext.plist. If AuthorizationClientContext.plist appears without a directory, delete or send to trash and empty trash.
follow the rest of the instructions to restart computer.
this worked for me along with an hour on the phone with Jean from support who was very helpful.
