If you did not save the original tax return with a unique name before amending the return, then the original tax return is no longer available on TurboTax as a PDF download.
The original tax return will be available on the IRS website.
For a fee of $43 you can get a complete federal tax return to include copies of W-2's, if you mailed the tax return and included a paper W-2, from the IRS by completing Form 4506 - http://www.irs.gov/pub/irs-pdf/f4506.pdf
