Allocate New York State Adjustments

[Diana36]

In 2023, I was a part-year NYC resident. When preparing the NY state return I came to a screen titled "Allocate New York State Adjustments". The text says: "Because your residence changed during 2023 you must allocate your New York State adjustments of $X based on the time you spent as a resident of New York City or Yonkers... Your New York State Adjustments below must equal $X." My spouse and I are filing jointly, the "X" number is his income only. What does it mean to allocate the "NYC Resident Portion"?
