Never use payment receipt as your judge of when to recognize revenue. The payment may or may not happen at the time revenue is earned.
Interestingly, you've said this wrong, but you're actually on to something. The journal entry is not for when payment is received. That journal entry is for when you would recognize the revenue. (You're credited revenue, so you're recognizing it.) But think about why you would have had something in the Unearned Revenue account to begin with.
