I think with MacOS 15 (Sequoia) the Mac's Finder autosaves document files that are open. The ability to turn Autosave off no longer exists in the System Preferences as it did in prior OS versions.
With autosave on, the App's File Menu supports a function to "Revert to Saved" as long as that file has not been Saved in the session. It seems that TurboTax might be Saving the file periodically inside the App? If it did that, the "Revert to Saved" function is disabled because prior versions no longer exist. Or put another way; whenever a User or an App saves a file, it defeats the ability to "Revert to Saved" versions. Perhaps your developers could check to see if periodic "Saves" are being done within the TT App?
Just a hint based on the behavior I am seeing.
