Expenses when Taxes and Insurance are included in mortgage

[Spencer Herrick]

When your taxes and insurance are already coming out of your mortgage, do you need to include them in the expenses on top of your mortgage payment? Seems to me that you wouldn't include them in addition to the mortgage as they are part of it. In Brandon Turner's Video on the Four Square Method, he mentions this briefly at 5:04 in the video and says he'll come back to it, but he never does. I've put a link to the video in the Description so you can see what I'm talking about. This really has me stumped so thanks in advance!
