I live in the UK and am filing an NJ-1040NR. How much of my 1099-INT is attributable to the state? Likewise on my 1099-DIV how much is attributable to the state?

I have mutual funds with Vanguard and Franklin Templeton. How do I figure out how much (if any) of my income from these is attributable to my state?

If you received all these funds while living in the UK, none are attributable to New Jersey.

As a non-resident, you are only reporting New Jersey sourced income, which these are not.
