QUESTIONS IN CREATION MATCH

I require matches 1 vs 1, whether friendly or competitive, without being a tournament.
I have entered the Teamwars / matches / add match, but when creating a new match the option to add opponents is not shown unless it is a team. what makes me have three questions

Q1 How to add a mach 1 vs 1 and add the registered opponents in the site?

Q2 How to add a map for the matches?
 
Q3 How to add a score to the match?

Thanks
