How to fix? Vendors imported into customers list and i need a report showing categorized invoices each check run

I'm here to help you sort things out, TessaT.

For us to inactive the imported customers (vendors), we need to zero out their balances. To do that, we can receive the payments and associate them with a dummy bank account.

Here's how to create a dummy account:

1. Click the Gear icon and choose Chart of Accounts.
2. Select New.
3. Under Account Type column. Under the Name field, type in Dummy Bank.
4. Hit Save and Close.

After that, we can record the payment through the Receive Payment option and deposit the payment to the Dummy Bank.

Or, we can delete transactions one at a time. Just open the invoice or bill, and click More at the bottom, then hit Delete. See the sample screenshot below.

Once done, we can go back and re-import your vendors. We can go through this article for your reference: Import customers or vendors from email contacts to QuickBooks Online.

On the other hand, we can generate the Transaction Detail by Account report to show all the invoices you need together with their corresponding categories.

I recommend customizing the report to get the specific details you need. You can also memorize it to save its current customization settings. It serves as your record and helps you quickly access it for future use. 

Should you need more help, please let me know, TessaT. I'd be more than willing to lend you a hand. Have a great rest of your day!

Ok, I will try that with the Customers problem.  When I try to run the report however this is what I am running into....

Thank you for the prompt response, @TessaT3773. 

It seems that you are trying to send us a screenshot for some clarification. However, no attachment that included.

Keep me posted if you need further assistance with your books. I’ll get back as soon as I can. Stay safe!

It shows Accts Payable where I need it to show the actual category splits....   Do i need to enter my invoices differently?

I appreciate the screenshot you provided, TessaT3773.

Let me continue to help you see the actual category splits of bills on your Transaction Detail by Account report.

Here's how:

1. Go to Reports and find Transaction Detail by Account.
2. Click the Customize button.
3. Under the Filter drop-down, check the box for Transaction Type and select Bill.
4. Check the box for Distribution Account and choose Accounts Payable (AP).
   
5. Click Run report.

This will show the category details of the split transactions.
