on my windows desktop Turbotax it's c:\users\user_name\documents\turbotax. if you are using W11 then when
if you see a file that starts with a "~" that's the backup file that's created (not sure in W11) as soon as you open or create the actual file. it can be used. if the laptop came with w11 preinstalled the default might have been to store documents on the web on one drive
