@Shengliang - I am totally confused by your post
1) when the RSUs vested, was that included in your W-2 wages (box 1). Yes or No.
2) when the RSU's vested, was the federal, state, medicare and social security taxes also increased on your W-2. Yes or no.
3) once vested the RSUs not sold to pay taxes are just shares. Did you subsequently sell any of the shares? Yes or no
once you post a response, I can explain what to do next
