Hello, buyinghomes.
For now, turning off the supplemental income is unavailable. You'll want to export the Transactions page to Excel and manually separate the supplement income from the income earned
Here's how:
- On the left panel, click Transactions.
- Select the Type, Bank, and Date from the drop-down list.
- Click the Export icon above the Action column.
- Open the Excel file and manually edit the data.
I've got a sample screenshot for a visual guide:
The other way is to categorize your transactions. You can read this article for more details: Categorize transactions in QuickBooks Self-Employed.
I'll be around if you have any follow-up questions or other concerns. Thanks.
