Default [Q] AT&T OTA Not working - Stock

Hey guys, I just bought this phone yesterday from AT&T. Just out of the box I received an OTA update, which I thought was the KK update. But no, I am stuck on android 4.1.2 and Sense 5.0, and when I try to update, all I get is a message saying that everything is up to date and there are no updates available for me.

I am on the AT&T network at the time, and my phone is completely stock, no mod whatsoever. Any ideas what is going on????
