gambling winnings nj

New Jersey resident received w-2 G for winnings in the state of New York

I entered my w-2 g in the federal part of turbo tax and it came up on sch 1 as income $2340.

Same number came up on my NY none resident return and i owe money.

Problem i have is on my NEW JERSEY RETURN where it comes up as  zero.

On NJ GAMBLING statement it shows like this:

1) Total gambling's                                                                 $ 2340

2)Total gambling losses (to the extent of winnings)         $ 2340 ( I NEVER ENTER THIS  LOSSES ANYWHERE)

THEY JUST SHOWED UP?  

3) Net gambling income                                                        $ 0

New Jersey Lottery winnings from prize amounts exceeding $10,000 became subject to the Gross Income Tax 

Out-of-state lottery winnings are taxable for New Jersey Gross Income Tax purposes regardless of the amount.

STANDARD DEDUCTION USED ON FEDERAL RETURN

2 questions

1) is it taxable ?

2)can i offset this with loosing lotto tickets purchased in NJ OR THEY MUST BE FROM NY
