New Dell Laptop here with same issues. Found a much longer thread addressing this issue from Dec 2, 2020, covering much of the same ground. Finally had success after trying almost every possible permutation of the options suggested (approximately in this order though desperation sometimes leads one astray from a purely logical sequence):
* Ensure Windows and drivers have latest updates
* Turn off all virus and malware protection prior to attempting activation with the following two steps
* Vary screen resolutions (I had 18 possible from 1920x1200 to 800x600)
* Vary scaling for each screen resolution (the number of allowed scaling choices differing for each resolution)
Nothing worked. I had originally installed TurboTax with my anti-virus protection on (TrendMicro--it asks me if I want to allow the program to make changes, and I had said yes), so I uninstalled it, re-booted, re-ran diagnostics and updates (Windows, drivers), and re-installed it with all anti-virus software turned off (very, very unhappy having been forced down that road). I then set scaling to 100% (using the recommended resolution of 1920x1200), and it worked....I was inordinately relieved not to call Intuit and be subjected to voice menu loops, and (I imagine) tech folks required to step you through all sorts of things you know to be irrelevant or have already tried.
Absurd--This longtime user is reconsidering future tax software purchases.
My system:
New Dell XPS 13, WIndows 10 (Home edition), basically just out of the box with almost nothing installed
