Hi, I was just billed 8.99 and need to know specifically what was purchased?

Start here→If you see 'apple.com/bill' on your billing statement - Apple Support

If that doesn’t resolve the issue here is a one-stop link for billing questions→Subscriptions and Billing - Official Apple Support. You can review your purchase history, check a specific purchase, manage subscriptions and request refunds.

Open the App Store --> click your profile icon in the top right --> select your name at the top --> select Purchase History.
