Welcome to the Community, noworry1.
You've come to the right place for assistance with QuickBooks. I'll gladly fill you in on how to have more than one business in the Self-Employed version.
Each business you'd like to have an account for does require a separate QuickBooks Self-Employed subscription.
The following link will take you to the plans and pricing page for this version of the software: https://quickbooks.intuit.com/self-employed/.
You're welcome to comment below if you have any other questions. Take care.
