Welcome and thanks for posting in the Community, @mdrounsavall.
If the DBA is the same business and with a different name, you can use the Class or Location Tracking feature in QuickBooks Online (QBO). This will help you track the sales transactions under the DBA.
To turn on the feature, please refer to these steps:
- In QBO, go to the Gear icon at the top right to get to the Account and Settings.
- Select the Advanced tab at the left, then tick the Categories section.
- Place a checkmark on Class or Location, then hit Save and Done.
For more information about the process, consider checking out these articles:
On the other hand, if it is a different business, you have to create a separate company or QBO account since they both have a different FEIN.
Reach out to me in the comment section below if you have any other questions or concerns. I'll be more than happy to help. Have a great day!
