Hello,
I'm happy you've contacted us in the Community for help. I'll help clear this up for you.
QuickBooks Online is designed to track your business expenses only, and isn't equipped to record personal expenses. I recommend consulting with your accountant to find out the best way to divide this expense so that you're able to enter just the business portion. Once you know how much your business expense will be, use the following steps below to create an expense:
1. Click the Create (+) menu.
2. Select Expense.
3. Choose the Payee from the drop-down menu.
4. Enter the category, description, and amount into the Category Details section.
5. Click Save and Close.
That's all there is to it! Let me know if you have any other questions, and I'd be happy to help.
Cheers!
