WHEN I PAID BILLS QB WAS SET TO CREDIT CARD INSTEAD OF CHECKS

Good afternoon DBS36, 

Thanks for reaching out to the QuickBooks Community! To correct this issue, you would need to delete or void the payments and recreate them choosing the right payment method.  Here's how:

1. Go to the bill and select View Online Payment
2. Choose to view, edit or cancel your payments.
3. You may edit or cancel your payment anytime before the payment begins to process on the scheduled date. Once the payment has started to process, you won't be able to edit or cancel the payment in Bill Pay.

I am adding this article that has additional frequently asked questions when it comes to paying bills online from QuickBooks Desktop.

@DBS36RE: the method of payment was set to credit card instead of checks. Now all my bills are marked paid, but no checks were generated. How can I mark these unpaid or set the payment to generate checks without entering all the bills over?

There's no way to mark a bill that's been paid as unpaid. The bills will show as paid as long as the payments that are paying them exist/continue to pay them. To make the bills unpaid again, you must undo the payment. So, to resolve this open the credit card account that was used and delete the credit card charge bill payments that were created from the register. Then go back to pay bills they'll be available to pay again.
