I did my taxes and missed one question of what I made in 2018 -I didn't have that at the time (I now know what that is ) it said I could send that in (not sure of the correct address for that) plus a W-2 came for my husbands long term disability that we forgot about which needs to be filed with the Federal return . what is the best way for me to do this , I have never had to Amend anything before ?
