Confused about how taxes work for a small business at age 19

(sorry for my ignorance in advance) one of my friends and I of my good friends have recently started a business we filed for an LLC and opened a business bank account but we haven't got farther than that
we are just extremely confused on what taxes we need to file for and if we even need to file income tax through the business and how paying ourselves works if someone could break it down for us it would be EXTREMELY appreciated
we are in Minnesota if that helps

thanks in advance
