Thank you for the update on your situation. Yes, our teams are working on this issue with TurboTax Desktop 2018 activation.
We are pretty sure Product support tried this with you, but, at this moment, what we can do is to ask you to verify your Internet connection and if you have an antivirus. If yes, please try to deactivate the antivirus and try again. If the issue persists, be sure to turn back on the antivirus and call Product support (something you already did).
As soon as we have an update about this issue, we will post here.
Thank you for your patience.
