The tag below your question indicates that you are using TurboTax Online. If that's true, see the following FAQ for instructions to view a PDF of your tax return for a prior year.
How do I view, download, or print a prior-year tax return?
If you used the CD/Download TurboTax software for the year that you want to view, and you have the .tax20yy file, the only way to view the file is with the CD/Download TurboTax software for the corresponding year. If you purchased the software as a download from TurboTax.com, you can download it again and reinstall it.
If you are unable to reinstall the software you could try TaxPrinter. You send them your .tax20yy file and they send you back a PDF of the tax return, which you can then print with Acrobat Reader. TaxPrinter has no connection with TurboTax. I have never used TaxPrinter, so I cannot make a recommendation. I'm just making you aware of it.
