If (and only *if*) you select the option for the program to divide the expenses for you, the program will split the mortgage interest and property taxes between SCH A for the period of time it was personal use, and SCH E for the period of time it was classified as a rental. It will not split anything else. So you will have to manually pro-rate the property insurance yourself for the SCH E. All other expenses are not split, and should not be split. Either the expense was incurred while the property was classified as a rental making it 1005 deductible, or it was not.
