I completed last year tax individual tax return with 1st time rental property converted from personal to rental. Personal days in home was 33 remaining days rented. Property type was 1 single residential home. Transfer data from 2020 to 2021. Began entering rental expenses under rental property Proseries who flash to say unable to take since property is not commercial property. Overlooked to address later. Finished entering information for return. No errors except one on the schedule E worksheet under   carryovers to 2021 smart worksheet letter A Section 179 carryover which has a message saying unable to take since property is not commercial. Three questions: If customer is renting the property in 2021 for the full 365 days, was I suppose to change the property type or will it remain the same 1? Note customer is not in real estate just renting property. Secondly, why is there an error on the 179 carryover if it transferred over? Lastly, still on the schedule e worksheet under the carryover by year section the carryover amount is a negative under year 2018 instead of 2020.prior year, why is that?
