Voucher checks don't print with the split details (description and amount if broken down). How do I enable this?

Hello there, joe445. 

There only specific details when printing checks in QBO. You can check our Voucher Checks and look into the samples on what's printed based on the information recorded in QuickBooks. 

When printing checks we can also preview it on what's being printed. Here's how:

1. Open the recorded Check.
2. Click Print check at the bottom of the Check page. 
3. Select Preview and print. 

For more details about printing checks, you can click this link. How to Record & Print Checks.

I'm here if you need more help. Take care!

Here's how to fix the issue -

Under the Edit menu, select Preferences

On the left menu, select Checking

On the right pane, select the Company Preferences tab.

Check the box that says "Print account names on voucher"

It is maddening that the official QuickBooks reps could not answer this in the past five years.
