Should I deduct a NJ 2015 Homestead Benefit Rebate check amount from my paid 2018 property taxes? The check arrived in 2018 for property owned in 2015.

In 2018, I received a check from the NJ Homestead Rebate Benefit program for property that I used to own in 2015.  Should I deduct the check's amount from the property taxes that I paid in 2018 and enter the balance as my 2018 paid property taxes?  The check is not NJ state income tax refund.
