My widowed mother (86) received a 1099-C dated Dec. 31, 2016, for credit card debt for my deceased father (2015) with only his name and his social security number. Her lawyer established with the credit card company (we have documentation) that the debt is only in my father's name and not my mother's. This debt is not on her credit history. No estate account was established in his name, and we did go through probate which is the Identifiable Event code used (#6/E). My mother filed my father's final tax return for 2015. For 2016 she is filing as a single person. My question: How do you file this 1099-C? Can I amend the 2015 return using a 2016 1099-C since it has his social security number attached to it? Thanks
