In invocie below the tax there is SR i need to remove that and put 5%

Welcome and thanks for posting in the Community, @perfectdieselshj.

When you turn on the Tax tracking in QuickBooks Online (QBO), the system will automatically create default tax rates for you. These are the taxes that will show in the invoice.

You have the option to add or edit the existing tax rates. Here's how to do it:

1. In QBO, go to the Taxes menu at the left pane to get to the Tax Centre.
2. Click on Edit tax in the top right corner, then select Edit rates.
3. Hit Save to complete.

Once done, you can now choose the new tax rate when creating an invoice.

To learn more about managing and setting up GST/VAT rates and use them on invoices and other forms, consider checking out this article: How do I set up sales GST/VAT rates and use them on forms? (International QBO).
