Good to know you know the rules.  Just not evident from your question.

Seems straight forward unless there's more that you haven't told us.  Maybe you are overthinking this?

Especially since the W2 is correctly reporting wages to NY as the SLR, wouldn't you just do the following on Screen 1?

• Resident State as of 12/31: NY
• Full Year Resident?: Checked
• Multi-State Return?: Check only if there is NC-source income
