Business & farm

How do you create a new form?  All I get are business forms.

I am the trustee for a trust that owns a single-member LLC.  The trust doesn't yet have an EIN because nobody died yet.  The trust owns the LLC, and the LLC owns the rental property. 

Also, how do you enter property tax expenses paid by the LLC as a business expense?  TurboTax doesn't ask for property taxes in the business expense section.
