I don't see a topic for simply reporting program bugs.
I had been working on my taxes, closed and saved the file. When I came back to work on them some more, I was in the folder where the file is located so I opened TT by double clicking the file instead of opening TT and having TT open the file. This created a 2nd copy of the file in TurboTax's recently used list. It's in both lists twice, under the File menu and in the "Continue Your 2021 Tax Return" box on the opening screen.
