I am assuming you selected the option to let the program do the splits for you. If you did, then enter both 1098's, all property taxes paid and property insurance paid for the entire 2020 tax year in the rental section. I do know for a fact that the program will split the property taxes and mortgage interest between the SCH A for the period of time it was your primary residence, and the SCH E for the period of time it was a rental. However, I'm not sure the program will handle the insurance correctly.
You "may" have to pro-rate the insurance expense on SCH E manually. Basically, property insurance on rental property is a deductible rental expense. Property insurance on your primary residence is not dedutible anywhere on your tax return.
Since you converted on Dec 1 2020, that means that 11/12 of the total property insurance paid in 2020 is a deductible rental expense. 1/12 of the total insurance paid in 2020 is not deductible anywhere on your tax return.
When entering the 1098's in the SCH E section of the program, there's some important details I want to make you aware of.
It is imperative that you enter the 1098 for the old loan first.
When when you enter the 1098 for the 2nd loan (the new refi) there will be a checkbox on one of the screens that you "MUST" select, that identifies this new loan as a refi. You "must" check that box. Please make sure you do.
