I thought I had made an additional post but I am not seeing that.
I tried approaches discussed above by simply restoring from backup and working on my tax file without indicating that I was amending my return. They produce similar but not exactly the same results.
Per @nexchap, since I did "not have any Ord Gain (Gain subject to recapture....), just enter 0 for everything" on the “Enter Sale Information” part of the K-1 interview. That does remove the extraneous Form 8949 and the double counted gain.
When I tried repeating that with the TurboTax "Amend return" capability, I found the TurboTax UI quite confusing. I went all the way through and generated a PDF to review, and that actually seems to make more sense. Still working it.
