Need to file robinhood taxes from 2016-2019.

I have been tax exempt for over a decade since leaving the military. I have messed around with the Robinhood trading app and have lost money every year until finally making it back this month(November, 2020). I am hoping to file these without spending hundreds because I am sure that what is owed is not much, if any, and robinhood is all that I have to file. Thank you!
