You can't efile a prior year tax return and you can't efile any amended tax return. You must print and mail all amended returns. 

Oh, so their 2017 Amend software tells me to e-file which isnt at all possible. Very good program indeed. Well it doesnt tell me where to send the tax return or anything, know where i can find that information?

Here is how to find out where to mail an amended return form 1040X: <a rel="nofollow" target="_blank" href="http://www.irs.gov/instructions/i1040x/ch01.html#d0e484">http://www.irs.gov/instructions/i1040x/ch01...>
You need to include any forms or schedules that changed with the amended return, the form 1040X, and any W-2s or other forms that had federal withholding that were added with the amendment.
