State tax filing

Thank you for replying. I’m afraid I’ve miscommunicated my message. Please see the screenshot attached, I was prompted to ask if I contributed my New York 529 saving in “Federal” or “New York Source Portion” which hestitated me because I understood, as you explained, federal doesn’t  take part in the insensitive for 529 plan. I contribute my 529 through BlackRock so I don’t know if which box should I select.
