In case it helps people, for the desktop version, turbotax 2020 premier on Macintosh, the software doesn't work correctly when you click the option to input all the data yourself (what Tom Young recommends doing). It will confirm the adjusted basis, tell you that it adjusted it for you, but then not actually adjust anything. In other words, double counting still occurs.

This is the option where it walks you through everything (using your 3922).
