Salary outside India for RNOR

I received salary outside India for 4 months and then came back to India and I have achieved RNOR status this year. Now this salary outside India is not taxable for RNOR in India.

1. Do I need to show this in my return and where?

2. How do I fill up schedule FSI (as I am not claiming any DTAA benefit. It's just that salary should not be taxable here in India)

3. I want to take the benefit of 115H and so ticked yes. Is there anything else I need to do.
