Cost basis=$182,905 for rental in service starting 9/1/20. TT says depreciation=$647. I think it should be $1,940. Is TT calculating it wrong

This is the first year I rented the property, placing it into service in September, 2020. I'm calculating as follows:
182,905 (cost basis)/27.5 (years)=6,651.09
6,651.09 (2020 depreciation)/12(months)=554.26
554.26(1 mo depreciation)*3.5(months)=1,939.90
