Problem solved:
1) The import functionality can be found by searching for "import" in the "Search topics" tool, accessed from one of the buttons at the top of the turbo-tax window. This may in fact be the same as last year.
Once I'd done that, it took me to something that looked like the "I'll explore on my own" UI that I remembered from past years. But switching to any other time lost it.
2) There are a number of must-answer questions that look like they are part of the interview, and block access to the choice between "guide me" and "I'll explore on my own" for each section.
Once you answer those all-important questions that aren't *really* part of the "guide me" process, you get the same choice that was available in past years.
So, I've been saved from having to buy two tax products this year.
