How do I know what RSU was vested?

This is a forum to discuss income taxes.  Your question makes no mention of income taxes - though I guess that's the impetus behind your post - and asks a question that literally no one here can answer.  You and your employer have all the details about any grants you may have received, and that includes the vesting schedule.

I'd suggest adding some background information here.
