My filing type is different for NJ state than for federal. How do I change my NJ state income, as the taxes will be different for my filing type?

Context: I stayed in NJ and worked in NY state in 2024. My wife worked in a different state for the entire 2024 and doesn't have any income from NJ sources. I filed my NJ state taxes as "married filing separately", but NJ state is counting my wife's income while calculating taxes. I have received a notice from the NJ state that I owe taxes; they are calculating taxes on the combined income that we used for federal filing. After contacting them, they suggested that I amend the return to include only my income during the filing period. When I try to amend the return on Turbotax, I don't see an option to update my income. It's still pulling in our combined income. How do I update the gross income, so that it only counts my NJ income and doesn't add my wife's income? TIA! Please let me know if any additional details will be helpful.
