You should have recieved an email asking you to confirm your address. Just reply to the email with your full shipping address .
If your address is not verified by Paypal, we will often ask that you confirm it to make sure the address is correct. Sadly, a large number of orders do get shipped incorrectly because the buyer does not send us their correct address when they make their order.
This process of asking you to confirm your address helps lower those mis-shipped orders.
