IDOC student's non-tax filler's statement

I’m filing out my IDOC form and I don’t have a job so I don’t file a tax. For student’s source of income, what am I suppose to write?

Did you say you would not file income tax in CSS profile?
You don’t have to do anything for IDOC. Just check mark the items you are going to send.
You can put “None” for questions asking for source of income.

Do you need to list allowance and gifts on the Non-filer’s Statement and submit that?
