1)House property - owner occupied 2) income from self employment

1) I am living in my 2BHK Flat.   There is no rental income.   In ITR Form 1 should I record my income as ZERO or record the probable renal income and property tax paid and show the final income as a negative figure.

2)   I am not doing any PROFESSION OR BUSINESS. I have small income due to self employment - such as Tution to children and mini catering to individuals.   Can I use Form 1  and Record this income under "Other Income" category.
