I've been experiencing the same issue with TurboTax Premier 2020 installation on my new Dell laptop, (i.e. blank Activation screen). But wait! There's more!
I first successfully installed TurboTax on my old laptop, (Lenovo ideapad running Windows 10 Version 20H2 upon receipt of the software ). Upon receipt of my new Dell laptop last week, I first uninstalled the software from the Lenovo, and began installation on the Dell. After multiple attempts, no success. I've attempted to 1. Repair installation, which generates an error code; 2. Uninstall/Reinstall; all without success.
After hours of frustration, and out of curiosity, I reinstalled on the old laptop without a glitch! I should also note that I was NOT prompted for Activation Code upon reinstall. So, is the Windows 20H2 really the issue? It's running on the old laptop and TurboTax works fine. Very perplexing.
I only now stumbled upon this post which I am hoping will work on the new Dell.
