How do I classify on Turbo Tax Business the asset of just land?

Classify in what way and for what purpose?

Land is an asset and although typically held as "investment property" (except where it is held for personal use), it is not subject to deductions for depreciation.

Land is classified as "land".  Land is not a depreciable asset  and it is usually not entered anywhere on your tax return or in TurboTax.

How are you using your land, in your business?
