My unemployment counts as income on my State return, but there is no income on unemployment in the state of NJ. What should I do?

During the past year I received unemployment in the state of NJ.
When I started my state return the unemployment amount counted as a gross income although the state of NJ do not tax on Unemployment. I spoke with the support and now one was able to explain why it is showing and how to remove it from the taxable income.
How should I proceed?
Thanks!!
