Thank you for the quick response. This makes sense.
When you say "when you are allotting your income between New York and New Jersey for the Part Year-Resident state returns, you will allot the income in the state where you physically were when you earned it.", how do I specify when I enter the 1099-NEC which states this was given for? I don't see an option of doing that, other than assuming the forms had information in boxes 4-7 ticked (which none of the forms had).
