I also had trouble running my copy of TurboTax Deluxe 2019 on my new laptop. The software would bring up a frozen activation screen with a blue dot.
When I reduced the resolution to 1366 x 768 as suggested, the activation screen was no longer frozen but didn't load completely (animation only).
I further reduced the resolution to 1280 x 720 and restared, the activation screen finally loaded to where I could input my code. After answering some basic questions, I saved the file. and restored my screen resolution to its native 1920 x 1080. The software updated itself again and needed a restart, but everything worked fine afterwards.
Thanks for sharing your solution so we have a place to start trying out other solutions like above.
