Are ;you asking about replacing the tax program on your computer or the tax return that you filed?

The 2017 Tax Return that I filed and which appears as an Icon on my desktop.

It is the program software that appears as an icon on your desktop not your tax return. You access your tax return (tax data file) by opening the tax program using the icon or you can see the files in the turbotax folder in documents. The program software will not do you any good without the tax data file ending in .tax2017 that you prepared with it.
