"Tom, I'm not sure you are understanding..."
You're not sure I'm understanding what?
My consistent answer in this thread was that while I'm sure once in a while mistakes get made, the Standard Operating Procedure for a vesting of RSUs is that shares are either withheld or sold "for taxes." If shares are sold then the cash goes back to the employer and that's what funds the taxes. And, more or less, the OP and another add-on poster both found out that was the case for them.
Now, maybe you're in the "mistakes get made" camp but there's not a single thing I can do about it. If this has been going on twice a year for the past three years there's a hell of a lot of money missing. If you didn't get the $10,500 then who did? Call up the broker and ask. If the broker somehow withheld taxes, (fairly rare), those taxes would be included in the "taxes" boxes of the 1099-B. Are there?
As "Deep Throat" supposedly said to Bernstein and Woodward, "follow the money."
