how to deduct cost of new roof on our house?? We use our home for 4 different businesses (home office deduction)

Hello! I'm confused about how and where to enter the $14,000 cost of our new roof ... because in 2022 we operated 4 businesses out of our home and take the home office deduction for all 4 of them. I thought a roof was a capital improvement that has to be depreciated for 39 years, but Turbo Tax is also offering the option to take a full or partial Section 179 deduction to expense it. I have no idea which option is better, and no idea how to handle the complicated fact that there's more than one business using the home. HELP PLEASE! I need an expert's specific step-by-step explanation of how to do this.  ðŸ˜µ

Thank you so much!
