I entered an M-1 adjustment for an expense that is nondeductible Federal, but deductible PA (Balance Sheet, m-1, m-2, m-3 > Schedule M-1, M-3 > Schedule M-1). Even though I'm entering -1 in the state box, it is still being listed as nondeductible on my PA return. I can override "Taxable business income or loss from operations" (State & local > Income & deductions > pa income/deductions), however trying to avoid that.

Is there a better way to enter this so that I don't have to enter any overrides?
