State tax filing

Thanks, ErnieS0!

 

Does it matter if the box16 number is different from the accurate amount earned in May-July?

Details:
I found that my box 16 is more than all the income from May- July. I think it is because I forgot to update my home address until Sep. I asked my payroll to fix the W2 last week but they just replied that they withhold based on the system's address, and would not change the W2.
