just to clarify how incomplete payment works:
Once the user make a submission to your form without completing the payment step, this submission will remain at the "Incomplete Payments" section until you complete it manually.
Once you manually complete an incomplete payment submission, it will be stored as a normal submission, you can call "incomplete payments" as "incomplete submissions" , so "incomplete payments" are individual submissions waiting for your approval.
Hope it clarify
