Tax Year Prior to 2020: Lost My Return

I finished my 2019 tax return.  I tried to save it on a CD, but during the save attempt, the external storage unit crashed.  My entire return was lost.  I checked EVERY possible place on my computer, but to no avail!  I usually save my return first in the TurboTax folder in "Documents", but I was in a rush and didn't do that this time.  I DO have the return's .pdf file saved, but not the .tax2019 file.  I will need that to transfer my information on next year's TurboTax program.  Is there any way that I can get a copy of that .tax2019 file?  Both of my federal and state returns for 2019 have been accepted.  I just wish that I could retrieve my .tax2019 file some how!  Is there any way to do that?  Thanks a million for any help you guys can give me!!
