If you have a .tax or .tax20xx file you need that year's Desktop program installed to open it.
Turbo Tax doesn't have programs older than 3 years. You might be able to find one on Ebay or Amazon or somewhere but you wouldn't be able to update it or download the state program.
You can ask Contact Customer Service 5am-5pm Pacific M-F

OR you could try the TaxPrinter service to convert a .tax file to pdf at

OR get a copy from the IRS -
