married filling separately, me and my wife each of us has a house under our name

Hi, everyone.

I am filing my state tax, but I have a question want to ask about property tax deduction - 

I and my wife are filing separately this year, we both have a house under each name. We are living in the same state, but living separately. My current house is my primary house, her house is her primary house.

I received a letter after I bought my house, indicating that Individuals and married couples are limited to one homestated standard deduction.

So I am confused that can I and my wife both fill the property tax deduction? or only one another?

Does property tax deduction = homestated standard deduction?

Thanks in advance!
