2024 taxes

My huband passed away in 2023, leaving a lot of credit card debt that i wasn't aware of. I live on my small social security, my only income. When i filed my 2023 taxes, i checked the box for last tax return for a deceased person (because i thought it would be and i planned to file a tax return just for me for 2024 on my social security income. Then yesterday i received a 1099C in his name. I live in California (a community property state). Tĥe form says he has to claim it as income. Do i have to file a joint return this year adding the $11,000 credit card as income? I can't afford to pay taxes, i don't have the money. Since the form is in his name, do i have to claim it on my return.
