What if I sold RSU at a loss? My total cost basis is calculated to be higher than the total proceeds. Can I put the numbers in Turbotax and list as Capital Loss?

I have 4 transactions of vested RSU as per 1099-B sent by E-trade. The first two trades result in losses (each cost basis is higher than proceed) and the last two trades result in gains (each cost basis is lower than proceed).  However, if I add the cost basis of all 4 trades the number is higher than the total proceeds. Should I put the corresponding numbers in Turbtax and list them as Capital loss?
