Manually change depreciation method for business use of home?
I filed my taxes with a CPA in previous years but using FreeTaxUSA for 2023 tax year. On my Schedule C my CPA has been taking depreciation since 2020 for my home office (business use of home) using the mid-month straight line method at 31.5 years. However, when I input my home office expenses using FreeTaxUSA (note, I put the date began using home for business as 01/01/2020), the depreciation method is automatically calculated using mid-month straight line method at 39 years. I noted that the IRS states that if you began using your home for business for the first time in 2023 then you should use 39 years but if began using your home for business before 2023 you should continue to use the depreciation method used in past tax years.
Is there a way to change the depreciation method to 31.5 years or am I out of luck?
