There might be a reason why you'd have something in your reference list from which you didn't use any ideas (quoted, paraphrased, or other), but I'm not sure what that reason would be!
You are correct! All citations listed on the Reference page must have at least one corresponding in-text citation within the body of the paper. This means that if you include a source in your list of references, you must also cite that source within the text of your paper. This is important to give proper credit to the original authors and to allow readers to easily find the source you used for your information or ideas. So, when you're writing a research paper or an academic document, it's important to ensure that every reference you include on the Reference page is also cited within the body of the paper.
