I have the same concern as @fanfare . If I am going to attach details, then I don't have a detailed transaction list that matches the format of 8949, which I believe is a requirement for 8949. Also on TurboTax I added cost basis to a couple of transactions so only TurboTax has the ground truth for what it puts on the generated 8949.
Wondering if it's possible that turbotax writes out the details directly rather than providing an aggregated transaction in this case. (Or let TurboTax generate a detailed list)
