Thank you for taking the time to post your concern here in the Community, @dtoczko .

Allow me to provide you with the troubleshooting steps to fix the option when sending your estimates.

Sometimes, too much cached files can cause the browser to behave abnormally. Let's access QuickBooks Online through a private window.

Here are some key shortcuts for accessing a private window.

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

If print or save is visible after this, the root cause of the issue must be from your regular browser. You'll want to clear the cache from your regular browser. However, if the issue persists, I'd recommend deleting the estimate, manually creating a new one, and resending it.
