Can i find how a particular check posted to an account?

Hi there, diana-berger-top.

Welcome to the QuickBooks Community. I'll be sharing various steps to ensure you can determine which account is linked to transactions.

If you mean how a specific check related to a vendor's transactions is posted to an account, I recommend running and customizing the Bills and Applied Payments report. From there, you'll be able to see an Account column to see which account is associated with the entry.

Here's how:

1. Go to Business overview and select Reports.
2. Use the Find report by name search bar and search Bills and Applied Payments.
3. Click the Customize button. 
4. Go to the Rows/Columns drop-down arrow. Then, checkmark the Account box.
5. Choose Run report.

However, if you're referring to knowing which invoice payments have been posted to an account, you can run and customize the Invoice and Received Payments report. You can look at the Account column to see which account is linked to the entry. Please follow the steps below.

1. Go to Business overview and select Reports.
2. Use the Find report by name search bar and search Invoice and Received Payments.
3. Click the small gear icon.
4. Checkmark the Account box.
5. Click anywhere on the page to save the changes.

Lastly, you may refer to this article on how you can memorize a report that allows you to save it with its current customization settings: Memorize reports in QuickBooks Online.

You can always find me here if you have other questions or clarifications with reports in QuickBooks or managing your entries. I’ll get back to you as soon as I can. Wishing you a good one, diana-berger-top.
