The DoFD is the date you first became delinquent and never brought the account current again.  It comes from the OC and is the same for the CA.  I didn't see it anywhere on your reports.

No, a 1099-C is not reported on your CR.  When and if you were to get one, it would count as income for the year you received it.

If you have no intention of paying them I would just leave it alone.
