>I am just looking for advice, how should I address the current situation?

I think you are making this a greater deal that in is.

You did what you did, you were given feedback on not to do it again (that is, sent to manager first). Your best course of action is to follow such feedback and move on with your life.

To be honest, I sense that your manager could have been a bit rude/strong by addressing that in a meeting and in the way you describe. He should have done that in private if his intentions were to teach you about something you did "wrong".
