I have also a brand new machine with Win 10 home 20H2; and have tried everything including this odd display resolution "fix". Activation is still not working and the logs keep pointing to certificate failures (see below). the screen is present and I can paste the activation key into it. the screen swirls but then fails.
The interesting thing is TT will install updates when launched but will not activate. I have tried turning off every firewall/security feature, placing the turbotax exe's in the exception apps, turned off wifi and direct connected, upgraded and verified all upgrades of Windows & Defender (security software) confirmed running as administrator. Certificates all appear to be valid and I can even get to the websites that TT is using to confirm internet access.
I am at a loss as to what or how to resolve this. If anyone has a solution to try, I would appreciate some help.
