pension distribution excluded from NJ State return

I am currently working full time , 64 years old and I get a distribution from a couple of small pensions. These are distributions from private firms.  Not disabled or a veteran. Income is less that $70000 per year.  distributions are taxed in the federal portion but coming up exluded in New Jersey. I have been receiving the income for 2 years. I googled this and it looks like it should be taxable.
