@GlobeTrekker818 Thanks so much for the work-around of going straight to the forms mode. That did the trick for my multiple ESPP transactions. What I found was that the relevant worksheet was already flagged for an error, since it was apparently missing info from Form 3922. Made it easy to find, and easy to fill in since I had the first ESPP sale as a model. And for everyone else out there, TT did indeed re-run the calculations all the way through after I entered the info.
I agree, it's scary to think that Intuit doesn't seem to respond to this rather serious bug in the interview flow. You'd think trust in their brand is their most important asset here, This really erodes that trust.
But a special shout out and thanks once more to @GlobeTrekker818 for the clear instructions.
