It is post Win10 update, but I find it hard to believe files sitting under MyDocuments/TurboTax would be auto-deleted (by either TurboTax or Windows). Oddly enough, I do still have one file in that folder "debug.log" from 2017. Nothing else is in there, and log file itself just has a few lines of log data (nothing of value). It's noteworthy because that means the whole directory wasn't cleared out. Just the actual .tax<year> files.
Unfortunately, I frequently empty my recycle bin. So, nothing in there. I'm just SOL (and royally pissed, of course).
Thanks for the suggestion, though.
