Having the same issue here. Tried all of the solutions earlier in the thread. I'm running a new Windows 10 machine 20H2 version and there were other problems encountered earlier in my taxes prep that I've found work-arounds for specifically related to this Windows 10 20H2 version. Resizing my screen resolution to 800x600 was one fix that helped solve an installation issue not being able to see the field to enter my activation code. Unfortunately I efiled my Federal and now I cannot get back to efiling state until Fed accepts my return. There is a bug fix supposedly coming out March 19, 2021 to fix this. I didn't get a chance to try changing my screen resolution to see if that fixed the issue. Hoping this problem here is resolved by then so when I can go back and efile state I can actually pay for the fee and file. I will be following/subscribing.
I'm using TurboTax Deluxe desktop/download. Windows 10, 20H2 version. I tried Chrome and Edge without success.
