Hi I'm new to quickbooks and just getting set-up, can anyone advise/tell me if it's possible to change/amend the Category or Match default names (with banking)?

I got the options to help you re-categorize your transactions, hello-lockerstas. 

Thank you for choosing QuickBooks as your accounting software. If they are from the Banking screen, just Undo them. Then, re-categorize and add them back to your bank account. Here’s how:

1. Go to Banking and choose the Banking page.
2. Select your bank account and click the Categorised tab.
3. Tap the affected transactions and click the Undo button.
4. Go to the For Review tab and select Categorize and modify the transactions.
5. Click Add. 

Here are a couple of articles that you can check out that can guide you in handling categories in QuickBooks: 

• Categorise and match online bank transactions in QuickBooks Online 
• Set up bank rules to categorise online banking transactions in QuickBooks Online 

Please let me know how things turns out. I want to ensure you're all set. Take Care!
