Filing taxes

I filed my taxes last night and went all the way through to the end, completed it. To where it told me I could track my stuff. Well I got a text saying that it rejected them, I went in this morning to try and fix it and it rejected it again. I can’t remember if I filed my taxes last year, so when the question came up i answered as I didn’t file it still asked me for a AGI, which I wouldn’t know because I didn’t file. I need help!
