If all Forms 1099-B (or all substitute statements) you received show basis was reported to the IRS and no correction or adjustment is needed, you may not need to file Form 8949. See Exception 1 under the instructions for line 1, later.
In my case, we have numerous accounts and form 1099-B's (all handled by Merrill Lynch). All were downloaded into Turbo Tax (as I have always done). All of them except for ONE account are reflected on form 8949(s). In this one account, there is one transaction with a wash sale. This one transaction went to a form 8949 and all the remaining activity (with no adjustments) showed up on Line 1a and 8a respectively. From the IRS Instructions, it appears you should only show activity on 1a and 8a IF ALL FORM 1099-B's did not have an adjustment.
There is 143 transactions in this one account. The information detail is in TT but I can't get it on a Form 8949. This is very frustrating, not to mention time consuming.
If I can't get this overridden in the system and a form 8949 generated, it appears that I'll have to attach the detail to the return in another format (copy of 1099-B for this one account noting the one item that actually is in the form 8949).
