Incorrect rental depreciation calculation by TT

I started renting out my property in Jan 2019, with building cost as 351804. In different years, I had different business use, sometimes 66%, sometimes 44% etc. For 2024, my business use is 33.33%. The online calculator using MACRS and SL, gives me a dep of 4,222. However, TT calculates it as 3575. Does anyone know why? My dep so far is 36673. Even last year, my dep. was incorrectly calculated by TT, but I let it be. I want to get to the bottom of it this year. Thanks!
