IRS instructions for Form 8949 are included in the instructions for Schedule D. It says this on page D-8:Quote from hj071:
I'm going to try importing the trade data (8949) and manually entering 1099 information into the tax software and see if it works.
"Instead of reporting each of your transactions on a separate line of Form 8949, you can report them on an attached statement containing all the same information as Form 8949 and in a similar format."
Apparently the Schedule D-1 has been replaced by the Form 8949. In prior years, the Schedule D-1 Worksheet provided by IB fulfilled the requirement of similar format in my opinion. If the new Form 8949 Worksheet does the same, then line-by-line reporting is being taken care of for us. Wash sales reporting will still be a problem, just as it always was.
