My husband & I both have an office in our home. Do I split our utilities and property taxes accordingly or do I put the full amount with both business?

I have an office I use 100% for business. My husband and I also share an office. (I have a computer in there I use for business). Do I split the utilities accordingly for both business' or put the full amount with both business (assuming TurboTax will know it's the same house and split if for me).
