Thanks for becoming part of the Community, Tammarito. I appreciate your screenshots, that helps me better understand what's going on.
 

When you create a sub-customer and enter a Print on check as name, what you entered will be used for their business title in your Shipping to field when creating estimates. This can be changed by editing their profile.

Here's how:

1. In the left navigation bar, go to Sales, then Customers.
2. Find the customer and click on their display name.
3. Click Edit.
4. There's a couple ways you can change their business title that appears in your Shipping to area on estimates.
   • By entering the correct business name in your Print on check as field.
   • By ticking Use display name and editing their Display name as if necessary.
5. Select Save.

Now the information you've entered on their profile will be displayed in your Billing address and Shipping to fields when you create an estimate for this sub-customer.

As for the business title that displays in your Billing Address field, you'll have to manually edit it and enter what you'd like the form to show. This is because when you select a sub-customer, it pulls information from their profile, instead of the parent customer.

I've included a couple resources about working with customer profiles and estimates that may come in handy moving forward:

• Creating & managing customers
• Creating estimates

I'll be here to help if there's any additional questions. Enjoy the rest of your day!
