Hello there, richwrightconstr,
I'm here to ensure there will be no duplicate transactions in your register.
It's possible that there's a manual deposit and at the same time, a downloaded banking deposit has been added to your bank.
If you have downloaded the deposits from your financial institution, QuickBooks categorizes the transactions as spent or received depending on how the data are shared by the bank.
You can undo the deposit and match it to the manually existing entry to avoid duplicates.
To manually match the transactions:
The system moves the transactions you matched from the For Review tab to the In QuickBooks tab and marked as matched.
Please refer to this article for additional information: How to add and match downloaded banking transactions.
By following the solution above, the duplicate payments in the register will no longer show.
Let me know if you're referring to something else by leaving a comment below.
I also appreciate if you can attach screenshots so I can get a better picture of the issue. I'm always around if you need help.
