Hi there, Lawn Girl.

Thank you for visiting the QuickBooks Community. This isn't the kind of experience I want you to encounter while updating the imported invoice. With this, I can share some troubleshooting steps to ensure that you're able to change the correct total.

A cache full of history and temp files can cause unexpected behaviors, such as being unable to change the exact line total. I recommend logging in to your QuickBooks account using a private browser. Then, try to reimport those invoices and update some details from the imported invoices from there. This is to rule out the possibility of a webpage issue, and private browsing doesn't store local files or cache.

Use these keyboard shortcuts based on the browser you're using:

• For Firefox or Microsoft Edge, press Ctrl + Shift + P.
• For Chrome, press Ctrl + Shift + N.
• For Safari, hold down Command + Shift + N.

If it works in incognito, I suggest clearing the cache of your regular browser. This removes the history or log of sites so you can start with a clean slate. You can check this article to see the steps: Clear cache and cookies to fix issues when using QuickBooks Online.

If the steps above didn't work, use another supported browser as alternatives.

Please refer to this article to see details on how the Sales page gives you the summary of your customer's transactions like open and paid invoices: View sales transactions.

Loop me in if you need further assistance with any concerns related to the invoices or any sales transctions. I'm always here to help you anytime. Take care and keep safe!
