Form 712

My husband found out after his mom died that she left a small policy to him for 11.000. He was informed a few months later by company. I think she forgot about it because she also had money saved for funeral in savings account. It had 22.00 interest because of the time of death and when he got letter. 

I know we don't have to claim money, it's under the amount stated of 14,000, and not taxed but what about the interest? It's small but how do we put that on TT?
