Hello, Kelleync.

Thank you for visiting Apple Support Communities.

This sounds like your Apple ID has not yet been used with the iTunes Store. Here is an article that I would recommend going through when experiencing this issue.

Use your Apple ID with the iTunes Store

1. Open the latest version of iTunes.
2. Choose Store > Sign In.
3. Enter your Apple ID and password and click Sign In.
4. Click Review when asked to review your information.
5. Enter your billing information.
6. Click Continue after you enter your credit card and billing information. You can remove or edit your credit card information at any time. Learn more about updating your iTunes Store account information.
