This year, as you have discovered, the Schedule D does not report
individual trades. Rather it reports summaries from Form 8949.
Form 8949 can report Long Term or Short Term, and a) Where Basis is
reported, b) where basis from stock sales is not reported, and
c) neither a nor b, such as a house sale or reporting the closing trade
of a call or put.
So in theory, there can be 2 x 3 = 6 separate Form 8949, and each
8949 can have many pages.,
I am hopeful the brokers will each supply 1099Bs in the same format
as the form 8949. and I can just attach them to the paper return or
to the efiled return using form 8453 as an attachment transmitter.
If they don't it's going to be a royal mess, and if some brokers
report nicely and others don't, those others are going to lose clients.
