Do you have the .tax2020 data file? Sorry even if you find 2020 to buy somewhere you probably won't be able to activate it with the License Code. The License Code started in 2019. So 2019 and newer needs to connect to Turbo Tax to verify the License Code. But they only support the last 3 years and have stopped supporting 2020 and prior. And you won't be able to download any updates or any state programs you might need. And you will need to download the state program to open the file.
OR you could try the TaxPrinter service to convert a .tax file to pdf at

They might be expensive and it is probably not safe to email tax returns back and forth. They are not related to Turbo Tax.
