Do you have the pdf of your return from the Online version? With all the worksheets? Sorry you can't get 2019 Desktop program installed and even if you did you wouldn't be able to download the state program. They only support the last 3 years. Support should not have told you to install the 2019 program. Where were you able to buy 2019? Maybe you can get a refund?
If you have the .tax2019 file and need to see the pdf of it, 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. I don't know if they can do State.
