How to get deduction for mileage with an LLC

My wife and I started a 2 member LLC last year, 2019.  This is the first year that I have done a tax return for the LLC, so I have some questions.  We have Turbo Tax Business.  We are the only 2 members and I was wondering how we take the deduction for business use of our cars.  I know how many miles were driven in each of our cars for business.  The cars are not owned by the LLC, though.  Is there a way to take the standard mileage deduction on the business return or personal return?

Also, can we do a home office deduction?  If so, how?  Any help is greatly appreciated.
