Hello, @myingling13. 

You'll need to go back to the actual company file to update the estimate. After that, set up your QuickBooks to create an Accountants copy. See the following article to know more about this:

Check the following article to know more of what you can and can't do in Accountant's Copy: Use the Accountant's Copy. 

Also, here's more information on how to create an estimate. Then, create progress invoices from the estimate: Set up and send progress invoices in QuickBooks Desktop.

Let me know if there's anything that I can help. I'm always here to assist. Have a great rest of the day!
