The Online version and Desktop CD/Download program are totally separate and don't sync. By the way, last year you could have moved your online return to the Desktop program so you didn't need to start over.
You need the file ending in .tax2018 on your computer to transfer into 2019, either into the online version or the Desktop program.
If you can't find your 2018 return you will have to get a copy from the IRS. See this IRS website for transcripts - http://www.irs.gov/Individuals/Get-Transcript
For a fee of $50 you can get a complete federal tax return to include copies of W-2's from the IRS by completing Form 4506 - http://www.irs.gov/pub/irs-pdf/f4506.pdf
