I had previously responded and am replacing this in case anyone else needs this info.
The link you provided actually explained this in more detail, so it's exactly what I needed! Thank you.
Here it is for those who need it:
Utilities and services. Expenses for utilities and services, such as electricity, gas, trash removal, and cleaning services, are primarily personal expenses. However, if you use part of your home for business, you can deduct the business part of these expenses. Generally, the business percentage for utilities is the same as the percentage of your home used for business.
