On the business use of home page where you list your utilities, etc. there is a line that says maintenance and repair - it goes there. Then that whole amount is totaled and that is what goes into the use of home equation.

Note that on the first page you also have a repair and maintenance line - the first one is for things directly for your daycare such as repairing the swingset or something broken by the daycare child like a screen in the door. The one on the use of home page is for things you do to the home to maintain it and then prorate that with the equation - the amount of space over total, number of hours, days one.
