This is a public user to user forum and it is not safe to post any personal info here or you might get spammed, scammed or worse. As I said the extra duplicate ~ tilde files ARE .tax files and not pdf files. You could even use it to transfer from.
The tilde files are temporary files which use to be deleted or at least hidden each year. But starting last year for 2015 return the programmers left them showing so in case your actual .tax file crashed you could get your info back.
