I would like to know the best way to track invoice numbers of the vendors that I pay on bank trans screen..especially under credit card feeds as invoices are emailed

Welcome to the QuickBooks Community, jrtlost. 

Please note that directly entering an invoice or bill number into the connected credit card payment in the Banking or Transactions tab is currently unavailable. Let me provide the best alternative way to achieve this goal within the QuickBooks.

You might consider using the Memo field to enter the transaction number. This allows you to track the invoice/bill number and quickly detect which entries have been paid or are due with the vendor statement.

Here's how:

1. Click the Transactions menu in the left panel.
2. Choose Bank Transactions.
3. Locate the credit card payment and click it to expand the page.
4. Go to the Memo field and enter the invoice/bill number like 0123456.
5. Click Add or Split to save the changes or updated information.

Once complete, I recommend running and customizing the Transaction Detail by Account report. This allows you to monitor, review, and trace the invoice/bill number you entered on the Bank Transactions page. I've added a screenshot below for visual reference.

In case you need steps on how to run a report that will reflect all payments made to vendors, you can read this article: Run a report with vendor totals.
