1099-C Please help!?

My husband passed away 2022.  A 1099-C came in his name for his canceled debt, which was from a credit card that he opened before we married, and my name isn't on.  I was told I had to include this 1099-C (of his) on my taxes but does this only apply if I am filing married/joint?  He had very little income in 2022 for a few months, can I file without him, married/single and not apply that 1099-C?  Again the 1099-C does not have my name on it.  So two questions, am I required to claim this 1099-C on my taxes either way that I file (joint or single) because I was married- or no?  There was no estate/trust/probate for him.  If I file married/single can I just disregard his income and his 1099-C?  I wonder which is more beneficial to me.. to claim his little income and include this debt relief 1099-C of about 16k, or me claim single?  Thoughts and advice? Thank you in advance.
