NJ State NONResident Capital Gains

My wife and I must file a New Jersey NON resident income tax return, in addition to our Federal and Pennsylvania returns. We are residents of PA. I have capital gains income that I believe is required to be reported in Column A on the NJ income return. However, I cannot get TurboTax to report those capital gains there, even though it accurately reports it on both my Federal and PA state returns. 

 

Although the capital gain income is not from a NJ source, my understanding is that I am required to report it to NJ still in Column A (I guess just so they know about it). Interestingly, TurboTax does report my dividend and interest income to NJ in Column A which I believe to be correct. I just can't get TT to report the capital gains in Column A to NJ.

 

Can someone please advise why TT is reporting divident and interest income correctly to NJ but not my capital gains, even though my capital gains are being reported correctly on my Federal and Pennsylvania state returns?
