No do not make the selection that you converted the property from personal to rental use because you are still using the property for both purposes (personal and rental).
Select "No" you did not rent this property the whole year, then enter the days it was rented at fair rental price and personal use days (all other days). (see image attached)
Along with any other expenses you enter the mortgage interest and real estate property taxes and TurboTax will carry the personal portion to Schedule A, itemized deductions. Do not make a second entry in that section of the return.
