Report the mortgage interest on the Mortgage Interest line in the Your Home section of TurboTax. Just click on "Add another Lender" if you've already entered mortgage interest on your primary home.
If you use your home purely as your personal residence, you obtain no tax benefits from repairs. You cannot deduct any part of the cost.
If you did not rent out your second home and used it only as your second home then not of those repairs or maintenance are are deductible.
