I am a student and I did not submit my taxes last year (but I have in years past), how will that effect my 2018 taxes?

My dad claimed me on his taxes in 2017, so I did not complete my own taxes because I knew I would not owe any money. My dad will be claiming me again this year on his 2018 taxes, but I do plan to do my own taxes this year too. Will I need to somehow file my 2017 taxes late before doing my 2018 taxes, or can I just do my 2018 taxes without looking back?
