Because you owned the rental property all year ("from the beginning of 2019"), the calculation for depreciation allocation is (196-10 personal use days)/196, or 186/196.
You should not manually override the depreciation entry. TurboTax will automatically calculate the correct amount once you have entered all the information into the Rental Property section of the software.
