I understand that the backup file (the one with a tilde [~] at the beginning of the file name) that's automatically created by TurboTax is now a permanent file, and no longer a temporary file. This backup file really came in handy this year, as my TT file became corrupted right before I was going to e-file my returns.
My questions: How frequently does TT automatically create this backup file? Does TT create the backup only when certain events occur, such as when I manually save my file?
Thanks.
