To me personally, its a bug, we should not be sitting with calculators and combining 4 mortgage interests.
Turbotax should have an option to indicate refinancing if you main home and combine all our statements.
For anyone new to Turbotax its confusing and may lead to unintentional higher tax bill, unacceptable.
