The program not longer makes that adjustment. It adds back the accelerated depreciation but does not deduct the allowable depreciation. How can this possibly be at this late date?
Just a suggestion, if Section 179 is not an issue, you might use MA return to gauge NH add-back. Fed-state difference should be about the same. Obviously, you need to check this but see "Form 4562 Depreciation Options" worksheet for states with similar limits. Otherwise, you can run Fixed Asset Manager for a NH F/A portfolio under "Other." [Yes, I know it's not a solution.]
And, since we're on the topic, be aware of NH's "one-of-a-kind quirk for 754 step-up adjustments.
Hope that helps.
