Hello, My book has many 0.01 overpayment to vendors in year 2019 and 2020. When I tried to clean these overpayment, the QBO doesnt show any transactions over 365 days.

Hi there, @ swang-wceforest-. 

Let me help you find the transactions in order for you to manage the vendor overpayment.

You can can run the Transaction List by date report for a vendor and customize the date.

Here's how:

1. Go to Reports.
2. Search for Transaction List by Date.
3. In the fields under Report period, select  custom to set the date. 
4. Select Run report.

I've attached a screenshot for your visual reference.

If the steps above didn't work, sometimes the stored cache and cookies in your browser can be corrupted leading to problems when opening websites like QBO.

Let's access your account in incognito mode. Below are the shortcut keys you can use depending on your browser type:

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

Once signed in, open your report again. If this works, let's go back to your regular browser and clear the cache to have a clean slate. If not, I recommend using another supported browser. It could be that your current browser has a temporary issue with QuickBooks. 

Also, you can customise your report to make it more personalise and include only the details you need. For the detailed steps, please visit this article: Customise reports in QuickBooks Online.
