How do I get a copy of my original return that was amended? I can only access my amended one on the website.

Using the TurboTax online editions, if you did not save a copy of the original tax return before it was amended then the original return is no longer available.

Or go to this IRS website for free federal tax return transcripts - https://www.irs.gov/individuals/get-transcript

For a fee of $43 you can get a complete federal tax return from the IRS by completing Form 4506 - http://www.irs.gov/pub/irs-pdf/f4506.pdf

Sorry Turbo Tax only saves the last one done.  You were suppose to save a pdf of the original return before you amended.  

To get back to the original return you need to download the .tax2020 file and install the Desktop program to open it.  Then you can delete the amended return and take out the changes to put it back.  

if amended online, the original Tutbotax is permanently gone otherwise if amended on your computer then if all your fees are paid you should be able to print out a copy.

you can get a copy of the IRS  - a tax return transcript, available on-line
