I need to make a correction on the company in Quickbooks. Is this possible?

Thank you for joining us in the QuickBooks Community, @cathie-hrfinance .

I understand the need to set up company details correctly in QuickBooks Online (QBO). For better understanding, first off, I'd like to ask what corrections you want to perform. Secondly, I'd like to ask also what area needs to be corrected. In the meantime, let me share insights about the Company setup in QBO. 

If you want to view and edit your company's name, address, contact info, or VAT number, you'll have to go to Company tab. Let me show you how:
 

1. In your QuickBooks Online, click the gear icon to go to Settings.
2. Select Account and settings.
3. Select the Company tab.
