Deductions & credits
No, don't enter the Real Estate Taxes paid twice, even though the amount shows on both 1098's.
The 1098's should have an Origination Date in Box 3 which should differentiate an Original Loan 1098 from a Refinanced Loan 1098,so the loan balances would not be added together. When entering your original loan 1098, DON'T indicate 'this loan has been refinanced' (even if it has).
When you enter your Refinanced Loan 1098, indicate YES this loan has been refinanced. You will then be able to indicate whether the entire loan amount was to 'buy, build or improve' your main home or you took CASH OUT in addition to refinancing the old loan (screenshot).
