State tax filing

Thank you so much. 
Two follow up questions:

 

1) it’s likely that I would only visit NY offices fewer than 12 times annually. Does that still mean I would allocate ? Note that I also visit my company’s other offices in other states for the same reason. How does that logic apply to state taxes?

 

 

2). currently, my company has not taken any withholding for New York. It’s all been for NJ. is there a way I can instruct my company to deduct accordingly ? 

3) I am working remotely most of the time especially. Is during the pandemic.  (I am considered “field based” in our HR structure). Does this change anything ?
