Yes, you can for interest and property taxes. However, it would be better to keep it separate as there are other deductions you may be able to take. Also, you should keep the loans as separate entries if there were any points paid on the refinance (see below). Keep in mind that the refinance usually results in a new account number so you should receive two 1098 forms.
Refinancing goes in the same area as your regular mortgage interest. When you enter the new mortgage interest, the software will ask you questions about the new loan and you will be able to select that it was a refinance.
You can deduct any interest or real estate taxes on your Settlement Statement that are not already included on your Form 1098.
Also, you can deduct qualified points paid on a mortgage, but they have to be spread out over the term of the loan. The software will prompt you to select that. (Points can also be called loan origination fees, maximum loan charges, discount points, or loan discount.)
What kinds of refinancing costs can I deduct?
