Turbotax is counting capital gains from stocks as sales of property on NJ form

When filling out the NJ State Return form with Turbotax, it's counting my capital gains from stocks as sales of property. Is this defect in the software/website? It gives me the option to omit those out in the next page, but I just want to double check before omitting them just in case there's some weird law where NJ counts capital gains from stocks as sales from property.
