I don't understand this question under payment Allocations. Enter the portion of the following payments attributable to the period when you were a New Jersey Resident?

Please clarify what the $620 represents.  My guess is that it is a payment that may not apply to New Jersey (NJ), unless you had withholding for NJ and/or another state.  Check your W-2s to see how much state withholding belongs to NJ, if any.

Put any additional notes here and we are here to help.
