I assume we're talking about your federal return here. If so, then the only place you enter property taxes paid on your rental property is on the SCH E, and absolutely nowhere else on the return. This is of course, assuming the rental property was "in fact" classified as residential rental real estate for the entire 365 day tax year with absolutely no days of personal use.
It sounds to me like you're entering the property taxes paid on your rental, under the deductions & Credits tab in the "your home" section. Don't do that. Or did you convert the property from personal use to rental property in 2019?
