"No TCC number required?"

No, we just logged in and were off and running.  But don't go changing your name ------------ with all of anvils that have hit me in the head, you might confuse me.

"Business efile shut down has not been announced yet"

No they haven't.  I'm not sure why they can't announce both dates at the same time, unless nobody at the IRS has figured out that date yet 😀
