You can probably download a copy of the original tax return transcript at the IRS website if you qualify to open an IRS account (or already have one.) If you can't establish the IRS account, you can order the transcript to come by postal mail in 5-10 calendar days.
An copy of the actual return from the IRS costs $43 and takes several weeks.

If you used Online TurboTax, we can tell you how to download/print a copy of your amended return with all the worksheets and extra pages, but it won't have the original Form 1040, and the forms/worksheets will reflect the changes you made when you did the amendment, not the original data.
