Does undefined work mean the work you complete or the work you didn't do relating to miles driven to fix up rental property?

[AmyC]

Undefined work is not an actual question. When you are entering a vehicle into the rental section, the screen asks for total miles driven in the vehicle, miles used for your rental, and the breakdown. Commuting miles are also a question. Any other miles driven are considered personal use. All miles are defined.

I wonder if "undefined work" is the title the program is using and you have a blank for a property or business rather than a name or address.
