Thanks DoninGA,

I am really concern on how and why the PDF file was removed from my computer Turbo Tax folder?

A TurboTax PDF file is no different than any other PDF file and it cannot delete itself.

Are you using the Online browser version or the Desktop CD/Download program?  On Windows or Mac?  Did you search your whole computer for it?  Check the Trash or Recycle Bin?  Do you use Drop Box or One Drive?

I use the Desktop CD/Program download. I checked the Recycle Bin and files were not there.

My Turbo Tax file include all previous returns except 2017, 2018 & 2019.

This happened to me too and not just my PDF files.  It deleted all of my tax files for 2018.  Here I am now in 2021 and yes, it did it again.  This time, I filed my taxes though and so I am now tryng to remember if I printed off a copy.  If I didn't I am screwed!  The original question is WHY is Turbtax deleting files when it updates?
