Land is a non depreciable asset that IS listed in the asset section however it is indicated as land which will not apply a deduction for depreciation.

Would I enter it as non residential?

Yes ... it is non residential  but only if it is part total cost of the buildings with land included in the purchase price.    If it is simply raw land with no barns or other buildings then you can skip entering in the land and keep the info in your records for later.
