@dmertz
dmertz - I saw that you replied and I caught most of your response, but I believe the post has been deleted. Could you repost please? I understand that I am able to amend back to my 2016 tax return (if done by April 15, 2020), but are you saying I can't amend my 2014 and 2015 tax returns MFS to MFJ? I know I won't get a refund for these years if owed one (since it is past 3 years), but I didn't think there was a time restriction for changing MFS to MFJ.
