Form 8829 is for your Home Office, not for a rental property. So it looks like you were depreciating a Home Office (but forgot to enter the land, which likely means the depreciation is incorrect). But that has nothing to do with your rental property.
Do you have a Home Office for a business that you report on Schedule C? If so, that is what that shows. If not, it looks like that is an error, in which case I recommend going to a tax professional to figure out things.
