What you have created is a non-expiring "request"... it's like creating an invoice and sending it to a client...
If all you want is an "address" that someone can send funds to, then click that entry in the list, then click the "address" tab at the top-right of the "Receive" page:
NOTE: It is only pending, because has detected that no funds have been sent to that address yet, so the "request" has been filled
So you will be able to receive the funds sent to that address.
Alternatively, you can use "View - Show Addresses" and then click on the "Addresses" tab and select an address from that list.
