I'm also having a problem activating 2021 Turbo Tax Deluxe on a Windows 10 machine that is nor being addressed by Intuit. I first tried using the software download version( which I returned). I'm now using the CD version and have tried loading on 2 different PC's. The program loads, updates, allows me to enter the activation (license) code, but then won't connect to the activation server. I've tried removing and reinstalling with no luck. What is about trying to connect to the activation server that causing this failure?
