I wonder if it is similar to an issue I've encountered this year for TT Home & Business 2020 dload version? Two of the screens for buying another state were too large for the display and were not Windows convention compliant. These particular screens would not resize the screen with ctrl- and ctrl+, and the corners or top and bottom could not be grabbed with the cursor.
Here's my workaround:
Let's get your billing address screen
After after entering your phone number, hit <tab> 4 times
then hit <enter>.
The next screen was ok. But then comes the
Great! Let's review your order screen
Click on a non-linked area of the screen.
Hit <tab> repeatedly until the first Edit in the upper left quadrant is highlighted.
Hit <tab> 7 times, then hit <enter>
All screens after this were ok.
