Thanks, Monica! The payment in question doesn't show up on the list when I click "payments" - but the most recent payment on the list is from six days ago, and I've made several merchant services deposits since then, so perhaps I just need to wait a few days?

But I just want to be absolutely clear on what I did: Several payments from clients who are on our automatic billing service showed up on the list today when I clicked on "Make Merchant Services Deposits". I dismissed one that I should not have, and received a message saying I could undo this under "settings". So - presumably in a few days I can follow the instructions you gave, that payment will still be listed, and I can 'receive' it at that time? Also, I need to be able to apply it to the correct customer account (changes in the ownership of the account are what led to this little fiasco). Will I be able to do that?

THANK YOU!
