I received a k1 form for 2017 in 2018 can I amend the 2017?

[Bailey6]

I was told that I cannot use this 2017 form this year. And used turbo tax in 2017. How can I amend that return?

How do I know which version I used online in 2017?

If you log in to TurboTax online, select "previous taxes" from the navigation bar on the left, and click on "2017" it should tell you what version you used in 2017.  The version is directly under "Filed Federal Tex Return".  Also, there should be a link to amend your 2017 return on the right side of the screen.

You have 3 years from the date you filed your 2017 return (or 2 years after you paid the tax due, whichever is later) to file an amended return, which means you don't have to amend your 2017 return before the 2018 filing deadline. More info

Depending on your situation, the first link and either the second or third link should help you:
