I had a company in 2018 and I dissolved it in October 2018 because I made $0 benefits. Do i have to file its existence too? could it help me to get a higher return?

Yes, you do, and yes, it might.

You have to file it with the rest of the money you made whether the business made money or not.  

Since you had zero income and expenses, you most likely will have a negative income, which you can subtract from your other income.  That makes your tax owed less, which will make your tax refund larger.
