How do expenses get recorded on turbo tax if I have 2 different 1099 PT businesses and complete Schedule C as well as have W-2 for other work?

I use the same office space and car for each one (they are related types of businesses). I've been asked to fill out the same home office and car expense info at least twice. I'm not sure if I should delete others and TT will pull from the one, or if I need to fill it all out for each business. My home and car info will be the same, just the percentage of usage will be different for each.
