Lost my .tax2019 file, etc. Have an IRS transcript for 2019. What info do I need to transfer from that transcript to complete my 2020 return?

I lost my hard disk and my 2019 .tax file and PDFs.  I have downloaded a transcript of my 2019 return from the IRS.  Does the transcript contain sufficient information to carry over deductions, losses, etc., from the prior year?  If so, what info do I need to enter ... Any suggestions would be appreciated.
