Look for the screens that asks for the number of days it was rented and the number of personal days. If you read it carefully, you'll see you should only enter personal days AFTER it was converted to a rental.
That means if it was converted to 100% rental, you'll enter ZERO personal days.
That also means you'll need to manually prorate all expenses, such as mortgage interest, real estate tax, insurance, etc. and only enter the prorated amount for the rental period.
