Thanks for letting us know. @Hope-younge-protr.
 

I'd be glad to confirm that matter to you.
 
In QuickBooks Self-Employed (QBSE) accounts, the option to grant multi-user access is currently unavailable. Each user is limited to one account. If you're utilizing a shared login and want to make changes to your QBSE profile, you'll need to do it one at a time. This allows you to accurately record your transactions in the system.

I'd also recommend sending feedback to our product engineers for our future product enhancement. 

Here's how:

1. Go to the Gear icon.
2. Choose Feedback.
3. Enter your comments or product suggestions.
4. Then, click Next to submit feedback.
