Excercised Incentive Stock Options - 4 sales on 1099B but only 1 Box V number on W-2 for adjusted cost basis

Extremely confused about how to handle the income from exercising my Incentive Stock Options. I finally exercised a few years worth of options, but Turbo Tax imported them and showing 4 sales on the Investment Sales page of questions. 

 

My 1099B shows 3 sales, with a box 1e "Cost or Other Basis (b)", and Gain/Loss for each.

 

My W2 also shows this as Box 1 income, and also a Box 12 V amount, which equates to how much my Box 1 value was above the income on my pay statements.

 

What I can't figure out is how to address the 4 sale in TT vs. the 3 sales on my 1099-B, and where I put the ONE Box V number into Turbo Tax.

 

How is this supposed to work?? Help! I want to be able to do this myself and not go to a professional on top of paying TurboTax Premier.

 

Thank you!
