How do I adjust my State w-2 wages for deferred compensation that is not taxable

I file income tax returns in multiple states. I am retired and a resident of New Jersey. I formerly worked in New York. My reported taxable W-2 Box 16 wages in New York equal my Federal Box 2 and New Jersey Box 16 wages. However, a significant portion of my wages represent deferred compensation distributions that are being paid to me over 15 years, and the distributions are not taxable in New York. In 2022, my former employer reported in Box 14Z the amount of my taxable New York wages, which excludes the deferred compensation distribution. So, how do I adjust my New York tax return to only be taxed on the taxable portion of my wages in Box 14Z, rather than the full amount in Box 16, for New York State tax purposes?
