NYS tax on capital gains from sale of vacant land.

  Keep trying to allocate land sale proceeds (long term capital gains ~78000) to NYS as a non resident. No NYC tax liability! My federal income is high enough that I should be subject to tax..

  Every method available during interview in TurboTax keeps refunding me all but $5 of the of the estimated taxes (9k+), already paid to NYS on my IT 2663, which then reflects as as tax due on my resident return in MS. The total tax looks right, but I would expect to pay it in NY not MS. 

  Does New York not tax capital gains on non-residential real property sales by non residents. If not, what section/form do I allocate this in. I’ve tried each different way I can find in the interview. 
   Thanks
