Does the placement of communications expenses change my refund? What is the best place?

Hi. I have a small business with a home office. I entered utility expenses NOT including phones and internet (communications)  under home office expenses, but I'm confused about where to put the communications expenses. I see a place that lists Communications expenses under Business expenses, but it shows that I didn't list anything there last year--so I'm wondering if there is another place that is better. Also, the utilities under home office expenses get multiplied based on the square footage of my office space--but if I enter communications expenses in the general Business expenses I assume there will be no multiplier; does that matter? Thanks!
