Hi there, Christiane.

At this time, QuickBooks Online (QBO) only allows entering products and services when creating invoices. Thus, choosing two income accounts isn't available.

As a workaround, you can consider creating two different items or services and associate them with their appropriate income accounts. Here's how:

1. Click the Gear icon, then select Products and services.
2. Select New, then choose either Inventory or Service.
3. Enter the name of the item and the necessary information.
4. From the Description field, you can specify if it's a "wholesale" or "retail sales."
5. In the Income account drop-down, select the appropriate income account you'll use.
6. Click Save and close.

Once done, you can repeat steps 2 to 5 to create another item for a specific income account.

I'm adding this article for more details: Add product and service items to QuickBooks Online.
