Unexplained AMT adjustment/preference for Rental Property depreciation

[constantine-vainstein]

I have a foreign rental property in service since 1/1/2022. Its price is 399,788, not including the land. I take 30 years as recovery period. In this case the depreciation should be 12,726. However, TurboTax adds an AMT adjustment/preference of $-19 in line 14 of Schedule E asset worksheet, and the resulting depreciation is 12,707. How can it be explained?
