Deductions & credits

My brother owed me money. he was terrible at money management. His credit score dropped. I had to end up hiring an attorney, and he signed off on a lien agreement that was filed with the town. I don’t even think he trusted himself paying me back that’s why he went to this degree to settle everything once and for all, he is in debt up to his ears so he did not have the funds to satisfy what he owed me. I appreciate being paid back, but I don’t know if I have to pay taxes on this since I was given a check by a closing attorney, I don’t even know if I’m gonna get a 1099S . It was just a flat number there was never any interest that I charged him.
