Thanks very much for your help.
Here is my situation:
I was physically working in California when I started this job, and in middle of COV I went to MA and worked from there but without changing my CA address etc. since I was expecting to go back to CA when COV ends.
At last year, I was laid off and HR requested my updated address at MA. And my last 2 paychecks happened after changing address. This might be the reason I got strange W2. I called them on the situation, and they are going to review it.
Yes, you are right. My current employer is still in CA and is aware of my telecommuting from MA, so only MA income and tax withhold are shown in W2.
Thanks very much!
