Business Mileage for one vehicle in two businesses (Schedule C)

Hi! 

I have one vehicle and two Schedule C's.

I am working on a tax return and noticed that after I enter total miles vehicle was driven in 2021, number of miles driven for business, and number of communting miles in BOTH Schedule C's, TurboTax is not calculating the number of miles driven for personal purposes correctly in each Schedule C.

Example of what TurboTax reflects after I enter the vehicle's mileage: 

Business #1

Total miles driven in 2021 = 6,111

Number of miles driven for business = 526

Number of miles driven for commuting = 4,696

Number of miles driven for personal purposes = 889

Business #2

Total miles driven in 2021 = 6,111

Number of miles driven for business = 346

Number of miles driven for commuting = 4,696

Number of miles driven for personal purposes = 1,069

Is there a way to fix this so that the number of miles driven for personal purposes is 543 (what it is when you account all business miles driven)?

Should I reduce the total miles driven in 2021 for Business 1# by the business miles of Business #2? 

Business #1 total miles driven in 2021 would = 5,765

Business #2 total miles driven in 2021 would = 5,585

Doing this would make the number of miles driven for personal purposes = 543 in EACH Schedule C

Will this cause any issues when I file my tax return?

Thanks!
