The 2020 tax data file with a file extension of .tax2020 can only be opened by the TurboTax 2020 software.
TurboTax does not have a process to produce a PDF from the tax data file.
The 2020 software can be purchased and downloaded from this TurboTax website - https://turbotax.intuit.com/personal-taxes/past-years-products/
However, there is a company that will do what you need for a price and is not associated with TurboTax or Intuit - https://www.taxprinter.com/
