and last year's depreciation
Just to confirm. Maybe last year was the first year you rented it? If not, then you should be entering the total of all prior year's depreciation. On the 2020 return that total would require you to add current and prior together, for the total prior to enter on the 2021 return.
Also check that you are using the correct original in service date as last year. A different in service date will skew things too.
Further things to check.
In In the COST box you enter the total paid for the property
In the COST OF LAND you enter the land value.
The program (not you) will subtract COST OF LAND from COST, to determine the structure value for depreciation.
Make sure those cost entries agree with the prior year return entries too.
