The interest portion is not deductible because it's being accrued, not paid; but the mortgage insurance amount shown on the 1098 is. My 1098 only had that figure and the "date of acquisition" field completed. TurboTax requires the original mortgage amount and date, so I used the date of acquisition for that and then used the amount of the reverse mortgage from my reverse mortgage closing statement from when I did the mortgage. I think these figures actually are irrelevant to the filing, but TT uses them to determine whether interest deduction should be capped. Since interest on a reverse mortgage is not deductible, this is a calculation TT shouldn't even be making, but since it does, you need to supply the numbers, since they are not required to be printed on this type of 1098.
