For a painting company, where would one deduce the actual paint purchased and used?

I am a sole proprietor for a painting company. Where do I deduct the material expenses? The section the says "materials" gives examples of stationary and the like.

The costs of paint that you used in your painting business (and not for resale) can be claimed as Supplies.

Go to Business Expenses > Other Common Business Expenses > Supplies.
