LLC business question

I have an LLC but I have no idea if I’m truly “using it” because the book I am launching this Wed 11/12 is copyrighted under my name, Sarah Vigue, and not the LLC, Meredibly. Therefore I’m not protected right?

I’m not sure how to “package” my copyright and place it in the LLC especially now… Am I too far gone? I read the article’s from Thomas on LLCs but I still have many questions, some of the same questions that were at the bottom of the articles that went unanswered so I’m not sure what to do.
