Am I also responsible to report on my taxes. It was not my primary and would probably end up having to pay taxes. My daughter is fortunate not to have to pay taxes as it was her primary.

If she was the primary and ALL of the discharged debt was reflected on her 1099-C, AND you can prove this, then you do not need to show the income on your tax return.

Expect the IRS to challenge your return, hence the need for the proof.
