It's nice to see you here, @developmentmari-,

2. Edit the URL on the address bar. remove everything after app/and enter purgecompany. For example: https://...qbo.intuit.com/app/purgecompany
3. Click Yes to confirm the action.
   
4. On the next page, select Wipe data.
   

Here's an article that contains all the information about the process: Delete your data and start over in QuickBooks Online.
