About my loan canceled due to TPD, what amounts or taxes do I have to pay as a result of the cancellation?
It is important to note that the date you are considered to be discharged is different depending on how you qualified for the discharge.
I just remembered that I forgot to inquire about federal student loans. Is there a list of requirements I must fulfill in order to be eligible for a discharge of my federal student loan?
Yes, certain eligible requirements are needed to get a closed school discharge  and you must apply for it.
