1099-C for Deceased Grandfather

Hello,

 

I hope I can obtain some help as I am not sure how to proceed.

 

My grandfather passed away in 2024. He resided in Louisiana with his wife. Both were on social security and were not required to file tax returns. We went through a succession and the property that he did have, a home and a vehicle, was transferred to my grandmother, his surviving wife. She is still alive. I am his grandson and I have been trying to handle his affairs.

 

There was a cancelation of credit card debt and we received a 1099-C. The 1099-C is in his name with his social security number, but he is deceased. Do I need to file this? If so, how do I file this? He has not filed a return in years - neither has my grandmother. 

 

Thank you!
