I can claim the MCC credit. Does Turbo Tax reduce the amount of mortgage interest claimed as a deduction by the amount of the MCC credit or do I do it manually?

My understanding is that if I can claim 20% of my mortgage interest as an MCC credit, then I can only claim 80% of my mortgage interest as a deduction.  Does TurboTax make that adjustment or do I manually reduce the interest (so it differs from the 1098 form)?
