Thanks for choosing QuickBooks Online (QBO) for tracking payments, @MelissaCatherine. I'm here to share some information about changing the category payment link

I know how important it is to change the category payment link. However, that option is unavailable in QBO. We can only change a category for a specific item. Here's how:

1. Go to the Gear icon and then select Products and Services.
2. Find the service item you want to change.
3. Select Edit in the Action column.
   
4. Click Change type.
   
5. Choose Non-inventory/inventory.
   
6. Once done, click on Save and Close.

For more details, please see this article: Change Product and Service Item Types in QuickBooks Online.

Also, I'd suggest reaching out to our QuickBooks Payments Team to check if they have an option to change the default. They can securely access your account and provide accurate steps. 

You can also check out this article to learn more about payment links: Accepting Payments in QuickBooks.

Additionally, I've included these resources that'll help you learn more about accepting electronic customer payments for online invoices and in-person sales. This way, you'll be able to track your sales record accurately.
