My bad i'm a bit confused by your questions, I barely know anything about taxes, so this is my situation I efiled for 2017 back in 2018 and it got rejected because of the AGI was wrong on the turbotax form (idk why since I downloaded my W-2 with the code) I wasn't able to fix the Efile because I checked on it too late, so realized I had to do it through mail, I researched how long could I wait before I had to file for my 2017 taxes and found that they give you 3 years to file it so here I'm 2020 trying to do it last minute.
Yes apparently I was able to file 2018 and just finished filing for 2019 without filing 2017 no problem
The only thing I'm trying to figure out is how do I do this, do I just fill a 1040EZ form with the correct information and attach my 2017 W-2 and send it to the IRS? or...
