@AunT .
i just checked my notes and I used my 2017 taxes to mark it worthless using the 8949 section when I efiled. This was when I thought it was correct to do it, because the company in question began that process in mid-late 2015.
Do I need to check for a certain event in the bankruptcy process to decide which correction route? ie amend 2017 or to edit the figure to 2019.
