Darn wish you were on a mac.
You have helped me learn things.
FYI and incase you have some similarities on your Dell:
when I right click on the icon I get a pop up box with lots of files, with "show Recents"
LOTS and lots of tax files there.
If you saved your file as a pdf (i think I have done this and overwritten my original with .pdf.... then it won't open with TT So I made this same mistake my first year using TT)
Such a learning curve!
In windows:
Go to your RECENT files and see what you can find.
Remember next time to save as and make duplicated before saving as a pdf.
If outside of turbo tax, in your files you clicked on it and renamed it with .pdf you (as the turbo tax expert who originally responded to your question says) you will have to re- in - put everything. At least you have the pdf as a guide.
Holy Moly Happy Tax time and Tally Ho!
