@ThomasM125 thank you. Just so I have that right, if my W2 says $6.6k of RSU (which includes all vested RSUs, including those sold for taxes) and my 1099B says $2.5k, and the supplement from eTrade shows the adj cost basis of $2.5k also, I would check the box you mention and change the cost basis to $6.6k?
