How to delete duplicate deposit?

First, why are there duplicates?  Do you have a payment or some other deposit QBO put in that did not match what the bank showed as the deposit?  Or did you just add one by mistake?  Be sure you know why they are duplicates before moving on. 

It is not uncommon for someone in a rush to accidentally accept a Bank Feed item that doesn't match what's in their register, but you need to confirm that it didn't match because of an error on the bank's part.  Deleting the wrong one can cause headaches down the road when things don't match up. 

If you are sure there is an accidental entry, then figure out which one to keep.  The correct one should be from the Undeposited Funds Acct or some Income Acct depending upon how you have things set up and how the deposit was entered into QBO.  But there should be a clear path on linking back to where the money for the deposit came from.    

The second entry, even if it has the little mark because it was matched to a Bank Feed is the one you need to delete.  It is going to be connected to some Acct, but if you go back into the transaction history it should not link back to a real deposit.  So once you're sure, just select it and Delete.

I applied a duplicate payment to an invoice that would still now be open. How would I unravel that mess?

I am trying to delete a payment from several years ago.  I cannot access it via the "banking feeds" page and this thing is just stuck in undeposited funds, not even showing up in my check register.  I cannot close out a month of reconciliation due to this mess.

How can i edit this transaction.  It seems really crazy that I have to spend so much time on something that I should be able to do.

Any help is appreciated.
