If you included an account/creditor in your bankruptcy, then it could be reported on your credit reports. You just want to make sure that it is reported as being included in your bankruptcy, with a zero balance. If you were late on the account before you filed your bankruptcy, then the late payments would be valid. But they should not report any late payments after your bankruptcy. They do not have to delete an account altogether because it was included in your bankruptcy, not until 10 years anyways.
The IIB accounts will fall off after 7 years from their DoFD. Hopefully that is soon for you
