I have spent hours entering data saved the lines several times now all is gone except the first line

Let's tackle this together with a series of troubleshooting steps to identify the issue you're encountering when entering data in QuickBooks Online (QBO), Caolan.

Before we begin, can you specify which transactions you are trying to enter data into and whether you've encountered any specific errors? Any additional details or screenshots you can provide will help us offer more precise and customized solutions.

First, try opening your QBO account in a private or incognito window. Your browser may occasionally store frequently accessed data, leading to unusual behavior on online platforms. You can use these keyboard shortcuts to open a private browser:

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: Command + Shift + N
• Mozilla Firefox: Shift + Ctrl + P
• Microsoft Edge: Ctrl + Shift + N

Once done, check if the data is visible. If it works, go back to your regular browser and clear its cache to refresh the website's preferences. Alternatively, you can use a supported browser to optimize your QuickBooks experience.

Additionally, to give you a snapshot of your financial records, you can run a financial report in QBO.
