Assuming what you say is accurate there are a number of issues that might favor you and result in a favorable outcome. You need to seek an attorney to assist you. He/she will review the reports and investigate as necessary.
You have some good offenses available to you contact a local criminal attorney for a free consultation. Now you know why you don't talk to police or investigators. Always ask if your free to leave and if the answer is "no" ask for a lawyer. Good luck.
You have an argument to make. How can you provide alcohol if there is none in the other person's system? Were there other minors in the room? Were there other people 21+ in the room? Was there alcohol in the minor's hand?
There are good defenses here.
Call a lawyer and prepare a defense.
