You can see your account's full purchase history via your computer's iTunes : See your purchase history in the iTunes Store - Apple Support
And if you owe iTunes money : Pay an unpaid balance in the iTunes Store - Apple Support
On your iOS device you can only see the last 90 days purchases on your account (and optionally contact iTunes Support if you have a problem with a purchase) via http://reportaproblem.apple.com
