We recognize the need to modify the default product/service items that QuickBooks generates for sales and time activities in your account, dollyc.

As QuickBooks Online generates an equipped default service item to track your sales and the hours worked, the ability to change them is unavailable, you may consider leaving this item as is. If the default item is an item that you've created, you can make a new Service item titled Sales or Service to replace the default so that you can make the other item inactive.

Additionally, you can check out this resource to learn how to manage default and special accounts in QBO: Manage default and special accounts in your QuickBooks Online chart of accounts.

Moreover, I'm adding this guide to help you check the total time or income from rendered services in your account: Run reports in QuickBooks Online.

We'll always be around in this thread if you require additional assistance managing items and accounts in your file. Just let us know in the comments below, and we'll be sure to get you covered. Keep safe.
