I ended up have a call w Turbo Tax support, and she directed me to jump to Schedule D, fill it in. After that, Form 8949 showed up (because I ended up with a small loss after accounting for all the fees) The problem is resolved.
I think it is a BUG in TT not to automatically trigger a Sch D & related forms. She won't comment on that at all.
See below if you need to see some details of how to find Schedule D. It is not obvious to me at all that is how one would do it.
I just have to click on "Search" on TT and type in "Schedule D" and hit return. Then click on "jump to schedule d". Choosing other items takes you to questions other people ask about the subject. However relevant, it is not the tax form you want. I am so used to picking an suggested search result as I start to type that I would not be able to see "jump to .." link if it is not for the help.
