After you file

Let's start over.  

 

1.  Did you file an original 2017 return back in 2018?  If not you do not amend.  You just file a new original 2017 return now.

 

2.  If the current 2018 return you did this year got filed and accepted then you need to amend 2018 and take off the wrong 2017 info and change it to just be for 2018.
