Question about filing taxes after being fired/unemployed

Im 20 years old and live in Indiana, I’ve been unemployed since February this year, I was working at walmart and filed my taxes for the first time this year in March. I havent had much luck finding a new job, and im kind of scared and at a point of accepting i’ll be jobless for a while and im in between wanting to work and maybe going back to school. I’m not disabled, I’m not in the military either.

How does one go about filing their taxes (if thats even an option) being unemployed for no particular reason other than not wanting to work and applications being ignored (at least it feels like it, i was unemployed for a good few months after I graduated high school).

I’m not planning to stay unemployed either, I’m just choosing to not work, I have no plans of working at the moment and have no idea how long this will last.

Last note, completely unrelated to my actual question.

Also if anyone has an answer about this question, I am particularly interested in entering the twitter model space (if ykyk, im not sure if i can say the white and blue site). Would it be possible to file taxes online without my parents or family finding out? Thanks
