It matters just "exactly" what kind/type of insurance you're talking about. Insurance reported in box 6 of the 1098 is called PMI (Private Mortgage Insurance) and is sometimes referred to as MIP (Mortgage Insurance Premium). This amount is entered in the same section where you enter the 1098 Mortgage Interest.
Now some lenders will report the property insurance (nothing to do with PMI/MIP) in box 10. They'll label it "insurance" or "Hazard Insurance" usually. This amount is *NOT* entered anywhere in the section where you enter the 1098. It's entered before you even get to the 1098 section of the rental expenses. As shown in the image already provided in this thread, one of the first two screens called "Enter Common Expenses" in the rental expenses section has a box labeled "insurance". That's where you enter the property insurance costs.
