Depreciation on rental

I have a rental property that I started renting out on 9/12/2016. The building value is 184,161. For years 2017 - 2020 I took a $6,747 depreciation deduction every year. For 2021 I got my taxes done by a CPA. For some reason the CPA came up with a depreciation deduction of $4,604 for 2021 and a value of 27,574 for prior years depreciation. For 2022 I'm entering a total of 27,574+4604 = 32,178 as my prior year depreciation in TT. TT shows me that I can take a depreciation deduction of only $2,341 for 2022. How's that possible when in the years from 2017 - 2020 I took a depreciation deduction of $6,747/year? How can I rectify this in TT by entering what I think is the correct depreciation amount of 6,747 for 2022? Or is my depreciation amount something else for 2022?
