I spent 3 evenings before finding this thread, blaming Turbotax, I will definitely switch to others next year.
Step-by-Step did partially work now, but there is still an issue: After it went through the questions form 1099-B it still asks you if you have reported the gain(which is calculated based on the incorrect basis by TT) on W2...I have to answer 'Yes' to avoid double taxed by TT, fortunately this question only shows up in worksheet, deosn't Form8949.
Hope Intuit entirely fix this issue sooner,.
