I am trying to duplicate an estimate in quickbooks online and I followed the prompts to actions and their is no duplicate action to select. Please help.

Hello there, ridgebackconstru. 

I recognize the importance of duplicating your estimate, ridgebackconstru. Let's perform some troubleshooting steps so that you can have the duplicate option.

Since you're unable to see the duplicate option on your end, we can open your account in incognito mode to see if this has something to do with your browser. Whenever you visit a website, it saves some information from the web page in its cache and cookies. These files allow the websites you visit most often to load faster.

Here's how to access incognito mode in some of the most commonly used web browsers:

•  Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Option + P

If you're able to duplicate your estimate by browsing privately, it's safe to say that it's being caused by the browser. 

It can be fixed by clearing your cache and cookies. In the event it continues occurring while using incognito, you'll initially have to try switching to another browsing application.

Here's a list of supported browsers:

• Google Chrome
• Mozilla Firefox
• Safari 11 or newer

Additionally, you can run an estimate report if you want to see all your estimates in your QuickBooks Online.

Keep me updated in the comments if you have further questions about your estimate in QuickBooks Online. I'm just a reply away. Keep safe and have a good one.
