Appreciate all your help so far @ErnieS0. So I took your advice and put all my paystubs in an excel sheet and separated by VA taxed and NY taxed. The number I end up getting very close to for VA was VA W2Box 16, and for NY was NY W2 Box 16 - VA W2 Box 16.
1. Does this mean my NYC Box 18 is incorrect and should I notify my payroll?
2. If I don't need to notify my payroll, should I adjust down now that I have proof that paystubs should add up to NY W2 Box 16 - VA W2 Box 16 for NYC Locality Wages?
3. As I finalize my NY Tax return, do I need to claim any credits taxed by VA to NY/NYC, or does the software take care of allocating it? I was taxed by both VA and NYC on portions of RSU and Bonus (10/22) after I moved to NYC. Bit confused on this part here.
4. Do I need to adjust anything on Federal portion?
