Hello there, @raleighkim.
I'm here to help you locate the list of custom estimate is stored in QuickBooks Desktop
Here's how:
- Go to the List menu.
- Select Templates.
- Locate your estimate template.
To restore missing customized templates, check out this article: File Location.
For an additional guide, while modifying email templates when sending messages from QuickBooks, you can also open this link: Create custom email templates in QuickBooks Desktop.
Keep in touch if you need any more assistance with this, or there's something else I can do for you. I've got your back. Have a good day.
