Anybody knowledgable about taxes?

So last year was my first tax year (not an American citizen and just got my green card and started working) so anyways I left my husband to do taxes as I haven't the first clue about them! Anyways I never saw any return, I know I was owed some but I never heard of my taxes again, husband doesn't have an answer for me! So anyways I want to file my own taxes this year but don't have a clue lol
