I've only been to the college campus about four or five times this year because of the coronavirus, and since I've been home all the time, I'm not sure if I'm a college student or a wanderer.

I have to take classes on the computer, which means I have to be home most of the weekday day, sos, and being home all the time makes me depressed!

nNext year, iI hope the coronavirus is over and that I am able to go to university,. I want to be involved in table tennis and fishing clubs.

"I am" is commonly written as "I'm".

There is the advantage of not getting caught up in the morning rush and not having to get up early in the morning is an advantage, but I still want to go back to university life as it was.

I can't wait to go to college in person.

This is grammatical. However, "go to college" generally means to attend college classes. You mention that you've been taking classes, so "college campus" (as in the physical location of the college), "attend classes in person," etc. makes more sense to me. This is different from "go to school," which often simply means going to school physically (not being absent).

I've only been to my college campus about four or five times this year because of the coronavirus, and since I've been home all the time, I'm not sure if I'm a college student or a wanderer.

See the comment before for "college."
"Wanderer" is grammatical, but it doesn't quite make sense in English. I think it would be better to just write the romanization "ronin" and explain what is it, for example: "I'm not sure if I'm a college student or a ronin, a secondary school graduate who isn't in university."

I have to take classes on the computer, which means I have to be home most of the weekday day, soday on weekdays, (and) being home all the time makes me depressed!

"So" implies that the clause logically follows from what you wrote before, but "being home all the time makes me depressed" is a

nNext year, iI hope the coronavirus is over and I am able to go to university, in person. I want to be involved in table tennis and fishing clubs.

- "University": Same explanation as for "going to college."
- "I want to be involved…" is a separate independent clause so it should generally be separated by a conjunction like "and," a period, a semicolon, a colon, or a dash.
- "The coronavirus is over" is acceptable to the average native speaker. You could also replace "coronavirus" with "pandemic" to sound more elevated.

The advantage of not getting caught up in the rush and not having to get up earlyNot needing to wake up early and get caught up in the morning rush is an advantage, but I still want to go back to university life as it was.

- "The advantage… is an advantage" is redundant. This phrasing makes more sense to me.
- Combining the two elements "not getting caught up" and "not having to get up early" sounds more elegant.
- Additionally, if you didn't combine them, you would have to instead write "are advantages," because there are two different advantages that you are describing.
