How can I see the estimate that have already been generated? i.e. where are they?

Hi faith-cactuscree,

QuickBooks Online is a powerful platform that simplifies the way you look at your accounting. I'll be glad to show you how to view your estimates so you can continue to manage your work with peace of mind. 

In order to view your estimates, follow the steps below:

1. Click Sales from the left menu.
2. Select the All Sales tab.
3. Click the Filter button.
4. Under Type, select Estimates. You can also enter other filter options from here to narrow down your search. 
5. Hit Apply when you're done. 

Give this a try and let me know what happens. I'll be one message away in case you have other questions.
