I agree that she's in Charlotte but don't know if they filmed today or not. I have no idea how I'd find that out either....maybe they filmed first thing this morning before she went to Charlotte? Maybe they're filming this even when she's done in Charlotte? Who knows...
I think the media got it wrong. shocking, huh?

It just seems unlikely to me that they'd film before this morning's show, since that time is spent prepping for today. Also, Kate would have to travel to Charlotte after the taping. Since she was scheduled at 1:30pm, she'd have to leave NYC pretty early to make sure she's there in time.
