How do you record an expense charged to a business credit card and allocate it 75% business and 25% personal?

Hello there, @Anonymous!

You can create an expense transaction with a line item for your business and personal account. Let me help you how.

1. Go to the Plus icon.
2. Under Vendors, choose Expense.
3. Choose a Payee.
4. Select your business credit card on the Payment account drop-down menu.
5. Enter the Payment date and Payment method.
6. In the Category details, Add a line item for your business and personal account.
7. Type in the allocated amount in the AMOUNT column.
8. Click Save and close.

I've attached a screenshot for your visual reference.

But, I still suggest contacting your accountant for the guidance and the specifications of each account to choose.
