All my past transactions are not showing anymore for the chequing account, how do I find these?

Hello admin328,

Glad to have you join the Community. It's important you're able to work with all your transactions so you can bring your finances into perspective using QuickBooks. I'll be happy to assist so you continue to manage your work with peace of mind. 

To get started, I recommend checking if you're logged into the right account. I also suggest checking if you're logged in as the right user as different roles have different access rights. In case this isn't the issue, I recommend troubleshooting the browser as it may be causing the issue at hand. 

Give this a try and let me know if this info helps. Clearing cache and cookies is a great way to clean your browser allowing it to work more efficiently. Here's an article that shows you how to do that: How to clear cache and cookies.
