Hi @RLKalman,
I am glad to see I was not the crazy one here! I have been grappling with this for all this while trying several things (like deleting the Box E trades and seeing their effect, changing Box E to Box D and seeing their effect, etc). Clearly, Box E is screwing up the way "Schedule D AMT" works in an atrocious way - my tax burden is several thousand dollars higher due to these Box E items - if I change Box E to Box D (nothing else), the tax burden goes down to what I was expecting and my AMT goes away as well. I truly believe this is a Turbo Tax bug. Going to reach out to Turbo Tax as @Anonymous_ suggested.
