Where in QB can I create an Expense Voucher for a payment to a credit card company where I have broken out expenses to various lines of projects/items?

appreciate your detailed information.

You can download a PDF copy of the payment remittance, then send it to your vendor outside of QuickBooks.

Here's how:
 

1. From the Expenses screen, click on your bill payment to open its record.
2. Hit Print at the bottom of your page. This will open a Print preview screen in a new tab.
3. Select the Download icon in your top-right corner. After saving a copy, you can attach it to an email and send it, or print it if you need a physical copy.

If you're using the Projects feature, you can review the information mentioned in this thread: How to set up a voucher system

Please don't hesitate to send a reply if there's any additional questions. Have an awesome Monday!
