I am having the same problem as the original poster. I sold three MLPs during 2023 and they are all showing up twice on form 8949. Is the advice on this post still good for tax year 2023? If I understand this correctly, the sale reported on the 1099-B needs to be adjusted and I only need to adjust the cost basis so that it equals the proceeds.
Do I only need to make these adjustments on the 1099-B, and I don't need to touch the K-1s at all?
