So I tried filing my taxes in 2019 using my 2018 w-2 but they were rejected because I did not know my agi for 2017 its now 2020 i already filed my using my 2019 w-2 I now have my 2017 w-2 so i know my agi and i want to amend my 2019 taxes but its don't show a option to input my agi for 2017 no more and I'm lost on how to do that will it reject my taxes and how will i know if the IRS reject them or not since I will have to do it by mail i wanted to efile it but it doesn't seem to be giving me that option
