The updater for 2018 won't initiate and hangs up thereby prohibiting me from completing a necessary Form 1040X. I now have Pro Series for 2019 and the future.

The updater simply does nothing when the dialog box is open. It shows 6 minutes, but doesn't update at all and I can't readily access 2018 TurboTax. How do I get the updater to work or simply access the 2018 software to work on the 1040X?
