Residential rental property depreciation does not add up in TurboTax 2021?

I am at the window where Turbotax asks about  "Cost", "Cost of Land" and "Date purchased". If I enter Cost as $540,000, Cost of Land as $500,000 and Date Purchase or acquired as 01/01/2020.

 

Then if in the next window I enter "Yes, I have always used this item 100% of the time for this business", then Turbotax calculated "Your 2021 estimated expense for this asset is $1394"

However, wasn't it supposed to be ($540,000-$500,000)/27.5years=$1454?
