After you file

OK.... I finished my 22 Tax Return....  I could not file as one form from IRS needed to be updated.  Today I got a note that the form was ready to download.  I up[dated as directed.  When the computer returned to my tax form... My Tax Form Was Erased..... I'd have to re enter everything again!!!!  I've searched the computer for my form.  ZIP.  I had used the CD form to enter my taxes.  AND none of the turbo tax downloads would open my taxes.  They all begin at step ONE......  HELP:
