Thanks for your reply!
My apologies for the confusion. Yes, I attached the Sch D and 8949 (just meant forms going along with 1099-B). I was unsure if the columns in part 1 of the 1040-X should have been left blank by TurboTax, as that's what the IRS highlighted (but it seemed they should have been left blank.) But again, I feel like I created a bigger production out of all of this by initiating the ammendment to begin with.
