Hello there, @deepak2508.

In QuickBooks Online (QBO), there's a red "Needs Attention" alert shown in the invoices when it's disputed. We can remove this alert by voiding or deleting the invoice, then creating a new one.

Here's how:

1. Go to the Sales menu, and select Invoices.
2. Find the invoice(s) that has the "Needs Attention" alert.
3. Click the Action column drop-down arrow, then select Void or Delete.
4. Hit Yes to confirm.
   

To know more about when to delete or void an invoice, refer to this article: Void or delete transactions in QuickBooks Online.

Once done, you can now recreate the invoice.

I've added this link about personalizing and adding specific info to your sales forms: Customize invoices, estimates, and sales receipts in QuickBooks Online.

Don't hesitate to post again if you have other questions about your invoices. I'm always here to assist. Keep safe.
