Turbotax backup tax file and turbo tax tax file

[Fit2]

Why is it that the backup tax file ( one with the tile) does NOT match the file opened and worked on.  I have these 2 files on my flash drive as well as a third tilde backup file that has the data all the way thru completing the efile all on flash drive. I use 5he flash drive rather than storing on hardrive or within turbo tax. This is all on desktop deluxe edition on windows 11 os.

Today I also notice that the file naming convention changed. It use to save taxfile with last name and first initial. Today's file save with first name and middle initial. 

What is going on with file saving and naming convention?

Don't know about the naming change...maybe some issues with working dependents, who have the same first name as the parent (usually the father)....that has caused problems with folks accidentally overwriting their own file.....using middle initial might eliminate that problem for most cases (but not all).

1) the tilde file ( ~ ), is not always exactly the final one....it is purposely a few steps (a few minutes or so) behind what you are working on, in case some disaster happens, you can recover "most" of what you've prepared.

2)  It is strongly recommended to NOT save directly to, or work off a USB flash drive...historically, those files have become corrupted during the save process, and become unrecoverable.  Certainly, things might have improved over the years, and perhaps they have some better interaction now...BUT (opinion) it's still safer to work and save to your main system disk, then copy-paste the .tax2023 datafile to the flash drive for backup.
