...and...one thing I noted at the very start of this year.
If you haven't actually started the initial interview for a 2021 tax return in your account, the "Tax Home" selection won't appear on the left side until you get started a few steps into the 2021 preparation interview. Doing so doesn't commit you to preparing and filing using TTX if you've already filed for 2021 elsewhere....but you have to at least start answering a few interview questions sometime since the 2021 Online tax software was initiated, before that Tax Home selection appears.

Of course, TTX might have changed that subtle requirement since then, but all of us helpers have gone way beyond that point by now, and wouldn't be challenged by that point anymore.
