How do I find an original return

I had to amend my 2019 return because of being told the wrong thing when dealing with TurboTax representatives.  Thank god I paid extra to be told the wrong thing.  Now, because the amended return that I filed and that was accepted by the IRS on September 30, 2021 but still has not been processed, I have to have my congressman's office start the process of finding out where my money is.  The only one available is the amended return.  I have to send in the original as well.  Where on this godforsaken site can I get the original return?
