Wages Allocation for NC & SC

Moved from SC to NC.

Still continued working in SC.

W2 Box 1: $100,000

W2 Box 15: NC & SC

W2 Box 16: NC $40,000 & SC $100,000

 

I don't understand why SC has the full amount. I don't want to pay double taxes.

How do I properly allocate these wages when they add up to more than W2 Box 1?


Do I identify each amount as PY NC Income or Not NC Source Income?

 

Thanks for your help!
