I just finished a 30 minute call with a representative about this same issue.  I see the new boxes for exceptions to reporting for short-term and long-term transactions with basis reported and no changes (Boxes A and C of form 8949) but these do not include boxes B and D of form 8949 which are items reported with cost basis not reported.  It appears that selecting code M in the detail below the initial input will allow for the old "Institution name - see statement" to be generated on form 8949 and no dates sold or purchased are required.  However, the form still requires a description in the first box.  This doesn't make sense because the form instructions show the description is being pulled from the top of the form Financial Institution name.  Can the programmers please change this so that no description is required in this box when code M is selected or change the instructions to place the name of the financial institution here or something that makes sense.  As I see it I can put anything in the description box and the error goes away but the information is not transmitted.  Has anyone else had this issue?  If you click the line item, you can do a manual adjustment on the detail form and also click the box that this is a code M transaction so perhaps that allows for wash sales and other adjustments.
