Ok, Thank you. It will only let me change the acquired date, it will not let me change the date placed in service. I entered information about both residences and stated that the house was placed in service on 9/1 and acquired on 8/30 and the apartment was placed in service on 1/1 and the usage was not more than 100% for both and not more than 12 months. I'm not sure if I should just change the acquired date, because on the form 8829, it's only showing me information for the house, not the apartment and only the one date is editable.
