This exact problem just happened to me. I have a new computer and the screen resolution was set to 1920x1080. My activation screen was frozen until I changed the system display resolution to 1366x768. (I chose that one because someone else had suggested it.) That was all it took to fix the problem. Instant success! After the activation, I changed my display resolution back to the recommended and the rest of Turbotax deluxe 2020 seems to be working normally.
