Thank you. Entering my numbers into the worksheet results in '0' for line 9, which after automated calculations gives me a negative value for lines 13 and 14 in Part 4. Which seems to make me ineligible. I assume this is something to do with not having paid enough property taxes in comparison to my mortgage interest to be eligible (e.g. NY State thinks I'm already getting a big enough deduction from my interest payments so I don't qualify for this extra tax break)?
