Core issue is something on the computer is blocking the activation request from the program from reaching the activation server. This is what I did and it worked.
Turned off Virus Protection (No effect)
Turned off firewall (No effect)
Turn off your my NordVPN (virtual private network: ie NordVPN) - That Did it!!!!!
Background: I had the same problem where the activation screen hangs with the spinning dots. Determined that it is because the activation cannot reach the server. I let it run all night and there it was in the morning. I bought my copy from Amazon. Then I called Turbotax and they provided me with their download. Both versions got stuck at activation. I have about 3 hours intuit (get it). Anyway, it was my VPN that was blocking it. All is good. Good luck!
