You're not supposed to see it, it's not available to the public. Right now the most current version is the GM.
 
I checked software update section in the settings but it says I am up to date. Is this iTunes only this time?

Yes. This has been answered countless times.

If you are on iOS 6 you will need to wait until the public release on the 18th to update OTA. If you are on iOS 7 Beta you will need to download the iOS 7 GM IPSW and shift-update/restore in iTunes 11.

You cannot go from iOS 7 Beta to GM OTA.
