Thanks go to VolvoGirl for actually reading the problem and making reasonable suggestions.
However, still no progress...
1. When I set up this computer a year ago, I made sure that OneDrive was deactivated.
2. The single account on this computer has Administrator privileges. So when I initially searched for .tax2023, that should have discovered any file that required an Administrator to see. And, specifically, using Administrator to start TT did not cause .tax2023 to appear.
Also, thank you for clearing up my misunderstanding about getting a notice of refund issue.
Now comes a fresh oddity...
When I started TT today, it asked to update Federal and Oklahoma files. If .tax2023 no longer exists, how did TT know I used Oklahoma forms? In my many years of using TT, 2023 was the only year I used OK forms.
