I want to go play football with my friends, but my brother is making me help him with chores.

The conflict is between the narrator and their brother: the narrator wants to play football, while the brother is making them do chores. That is character vs. character, because two characters have opposing goals. Character vs. self would involve an internal struggle, and character vs. society would involve conflict with a larger group or social rules.
