Deductions & credits

The issue with solar panel credits has been resolved, but now I am running onto a new issue:

We upgraded our furnace and central air system inner second home.  Turbotax is now (correctly) showing a credit of $1200 for this (form 5695), but after finishing with all credits and deductions it eliminates this credit (incorrectly).  I assume this is because the "energy improvements" credit is limited to one's "main home," and turbotax is also applying that limitation to residential energy property, but the IRS website and the instructions for from 5695 are pretty clear that the "main home" limitation does not apply to residential energy property (HVAC equipment).  Can this be fixed or overridden??
