If you paid a lump sum premium for mortgage insurance from the VA or the Rural Housing Authority (called a funding fee) that is deductible in the year you close. Other lump sum mortgage insurance premiums must be spread out over 84 months and deducted when you make your monthly mortgage payment. Your bank is supposed to put allocated lump sum PMI on the 1098 but not all do. If your bank did not, you can enter the premiums yourself. Be aware that turbotax does not keep track of the 84 month deduction, you need to do that yourself. And the mortgage insurance deduction also has an income limit so not every one will qualify.
You can add the allocated amount to the monthly PMI amounts. But make sure you are really talking about PMI, and not hazard insurance (fire, theft, etc.) While many lenders are not allocating the lump sum PMI to box 5, they really should be putting the monthly payment there if you are paying it.
