Hi there, ccmagna1.

Thank you for visiting again the QuickBooks Community. I'll be sharing details about budgets in QuickBooks Online and how it works. Then, to ensure that you're able to include Note repayments (from a Note Payable) from a Budget.

In QuickBooks Online, you can always create budgets based on your accounting data. Once your budgets are in QuickBooks, you can review and adjust everything. Furthermore, all of the lines that appear on the budget page will be determined by your Chart of Accounts (COA). That being said, there is a way to include Note repayments (from a Note Payable) by adding an account to the COA.

Here's how:

1. Click the Gear icon and select Chart of Accounts.
2. Click the New button in the top right corner. 
3. Click on the Account Type drop-down to select the account type.
4. Select the Detail Type to specify the type of account that you want to add.
5. Enter the name of the account in the Name field.
6. You have the option of including information in the Description field and an amount in the Balance field. 
7. Click Save and Close.
