Hello there, @aaronandrews218. I know a way to fix or remove inactive services that appear on your list while adding time in QuickBooks Online (QBO).

Inactive service items should no longer appear on your list in the Service drop-down menu when adding time activities and in any other place that displays (i.e., reports) them in QBO. Then, when you merge two services, one of them will be inactivated (deleted) from the products and services' active list.

Based on your description, I can tell that some of your merged service items are activated. That's why they appear with the same name with a number 1 after them. Please see and compare the screenshots below for your reference.

With this, you'll want to make sure your merged service items are inactive (deleted). This way, they won't appear on your list in the Service drop-down menu when adding time activities. To do this, here's how:

1. Go to the Gear icon.
2. Select Products and services.
3. Find the activated merged service item (with the number 1 after their name) that you want to make inactive.
4. From the Action column, click the drop-down menu and select Make inactive.
5. Click Yes to confirm. 

For more details about modifying your products and services in QBO, you can refer to this article: Remove or merge a product or service.

Also, you may want to checkout this article as your reference in case you want to group your products and services into categories to keep things organized in your QBO account: Group your products and services into different categories.

Let me know if there's anything else you need or concerns about managing service items and recording time entries in QBO. I'm always ready to help. Take care, and have a great day, @aaronandrews218.
