North Carolina computes taxable income based on federal adjusted gross income. Since the sale is part of Federal AGI it is included and taxable for NC purposes. However, you should also check with your tax accountant to see if any of the adjustments to AGI on the NC D-400 page 2, line 9 would help you.
Hope this helps.
