After you file

What is your saved file-- is it a PDF or *.tax2014 data file?  

 How did you prepare the return originally--in Online TurboTax or in desktop software (CD/download)?  
If you used desktop software, do you no longer have the 2014 installation file?   If you purchased it from TurboTax, the 2014 download should still be in your account.  We can tell you how to find it.

If you did not purchase it from TurboTax, we can tell you how to phone TurboTax Support to ask for the download.
