If you used the Desktop CD/Download program on your PC then the only copy is on that computer and any backups you made.  Not stored or saved online.  You should have saved a pdf file when you were done last year (and even if you used the Online version).  If you don't have a pdf file you should have the tax data file ending in .tax2019.  The files should be in your Documents in a Turbo Tax folder.  

If you can't find a copy, You can request a transcript from the IRS
