Yes, you can remove the standard account by selecting the appropriate product when signing in. Typically, you can log in to other QuickBooks products using your QuickBooks Self-Employed (QBSE) account credentials.
You can go to selfemployed.intuit.com/home to log in to your QBSE account and bookmark it for future reference.
Alternatively, you can switch to QuickBooks Self-Employed through your Intuit Account Manager. Refer to the How to fix it section in this article: Switch to QuickBooks Self-Employed if you signed in through QuickBooks Online.
