My aunt passed and I received a 1099-R showing $559 federal tax withheld on $16088 gross distribution and box 2a shows a taxable amount of $5588. Do I add this to income?

I am on a disability pension and just need to know if I don't include this since it is a death benefit paid from a life insurance company or if I list this 1099-R with income. I see that death benefits are generally not taxed. She was in PA and I am in OH. Thank you.
