Retirement tax questions

My father passed away and was owed one month's social security, which was eventually paid, but the SSA sent equally divided checks to his three heirs, instead of sending the entire amount to my father's estate account per the Executor's request. Anyway, I received a 1099 from the SSA with my name in Box 1, my social security number in Box 2, the amount of my third of the benefits in Box 3, NONE listed in Box 4, the amount of the benefit in Box 5, my name "on account of my father-deceased" with my address in Box 7. I know no money is owed, but how do I keep Turbo from assessing a taxable amount if I include it on my list of 1099's associated with my social security number? I don't see a way to show it as a nontaxable entity from an estate using Turbo. I could ignore it, but the system might Red Flag the IRS if it is not included, even though no taxes are owed. I do not wish to trigger a problem if there is a way to avoid it by how I show it now. Thanks so much for your answer. I hope the above explanation helps! I know I cannot be alone with this issue.
