1098 entry

am I supposed to enter the total 1098 mortgage interest for rental property expense or do I divide the rental property expense between rental and personal use for a second home? It asks for my 1098 in both the rental section of income and again in the Deduction section for a second home. I cannot figure out if TurboTax is doing the calculation for me appropriately or if I have to manually calculate percent use for personal reasons? Thank you for your time
