how to sign out of iTunes

I have two accounts with different logins with Apple. iTunes seems to be signed in to one of them and all the rest of my Apple world seems to be signed into the other. I don't see how to sign out of the iTunes. I am directed on iTunes to go to the Apple.com to sign in or out. I see there that a different account is listed as signed in to than I see on iTunes.

Thanks for your help!!!
