Deductions & credits

I have a rental property and placed an asset in service in 2019 with 5 year depreciation.  On my 2019 returns, the depreciation amount was calculated to be 1/5 of the total value.  However, for my 2020 returns, the software calculates the depreciation to be much higher than in 2019.  Shouldn't it be 1/5 for each year of the 5 years?  I checked the total value and the number of years for depreciation, no errors.  Shall I accept the amount automatically calculated?  If not, I can't find where I can manually change the depreciation amount (since the total value and the number of years for depreciation are correct).
