Cost Basis for RSU "sell to cover taxes"

I had an RSU vest this year, and elected this "sell to cover taxes" option. This sell appears on the 1099-B. So, TurboTax imported this from E-Trade for me, but complained about an empty cost basis field. My form had it as $0.00 is this correct?

Also, I am confused as to how this sell of shares is reported so that the taxes are right?
