I am trying get a specific answer to this question.
I am filing 1040X (using most recent form from Jan 2019). Along with 1040x, I also need to file form 6781 and schedule D to show the changes.
Question is: Do I use 6781 and Schedule D from 2015 (I will have to search for it online) or do I use the latest versions (which are readily available on IRS website)?
