How do you expense Mileage in QB Online Ledger?

I'm using Quickbooks Online Ledger - which does not include the mileage capability. It does however include the ability to create Expenses without having to do a Journal Entry (which is good b/c I'm new to accounting and Journal Entries are confusing as hell). 

All of my other expenses were paid with a Credit Card, so the dropdowns worked for me doing +Add Expense.  For Mileage however, I paid out of pocket, and my business does not yet have the cash to pay me back, so I want to enter it in as Money owed to me (the Owner), and Categorize it under my Account for Travel Expenses:Mileage, but the dropdown for Payment Account doesn't list anything I can use. It doesn't list the "Other Current Liability" account I created for Money due to Owner. I only see Bank, Credit Card, and 3 Notes Receivable accounts that I set up.  Should the Money due to Owner also be listed as "Other Current Asset"?  I can't figure out how else to get it to appear on the Payment account list. 

Thanks!
