Depreciation calculation

I have an issue with the depreciation calculation in my 2023 tax return. Here are the details:

Cost: $1,353,000

Business use: 26.5%
Depreciable Basis: $358,545

Life: 27.5

Method/Convention: SL/MM

As I understand it, the depreciation calculation in this case is

$358,545/27.5 = $13,038.

 

However, TurboTax has calculated the depreciation as $27,878. 

What is correct? If TT is correct what are the numbers behind it’s calculation.
