401k restoration plan

I received a payment of $79.57 from a restoration plan associated with my 401K. I received the payment because I made more money during my years of service. It was designed to compensate my 401k. I received the money one year after I retired. I got a check in July 2021. Do I need to enter that amount somewhere? I made $19.61. My balance in April 1, 2020 was $59.96 and then by the following year  03/31/21 the balanace was $79.57.
