Maintaining amortization schedule for points paid for multi-family mortgage

I paid points to reduce the mortgage rate on a multi-family property.

I live in one of the units and rent out the rest. 

How can I maintain the amortization schedule in TurboTax?

I have to split the amortization b/w Schedule A and E.

And my usage varies from year to year b/c some of the units are out of service for gut renovations.
