RSU Confusion With Sell to Cover and 1099-B

I am a little confused about how to report on my RSU activity. I had 100 RSUs vest last year. My company sold 30 to cover the taxes. This a very common situation. 

Turbo Tax imported from Fidelity a 1099-B with the sale of the 30. But it looks like proceeds that need tax withheld as a short-term gain. The cost basis on the 1099-B is $0. I do have information on the sale price of the shares from the transaction.

Should I enter that sale price as the cost basis to net zero out? Do I edit the "Total Shares Vested/Released" to be just the 30 and not the 100? I don't see a reference to the 100 anywhere on the 1099-B. It's on the distribution statement and W-2 showing taxes withheld for them. Should the "Price you paid per share" be the same as the "Market price on vesting date"? Somewhere I think things need to balance to a net of zero since the taxes have already been paid. But I'm unsure how. Do I *not* report these as RSU transactions? Very confused.
