@Just-Lisa-Now-  "If it's got wash sales you can't just stuff it in the boxes at the top of the 1099B worksheet."

Why not?

If the point is to get it past some tax examiner in the Automated Underreporter Program at a Service Center, all they are going to look for is whether the gross proceeds match what is reported, and if the gain on covered transactions is at least as much as what is reported.  If the gain is higher, the Manual tells them not to make an adjustment. 

IRS can create paperwork burdens to a certain extent, but when it adds excessive time and cost then we are fostering voluntary compliance by using a shortcut that doesn't change the amount of tax owed.  Until someone tells me to stop, I'll just adjust the cost basis of covered transactions to take into account wash sales.
