I broke down and opened a dummy return to see this mess. 

When you are on the 1099-B w/s, the NEW (and improved!) way to enter stock sales, enter the name, dates, sales price and cost, but DO NOT ENTER THE ADJUSTMENT* AMOUNT HERE.

Instead, double click on Adjustment Amount* box and go to Capital Gain(Loss) Adjustments w/s. Go to Part III and enter correct basis. 

Then the correct adjustment will appear on Sch D and 8949.
