Hello @jk-alam,
You can undo the online transactions accidentally added via the Banking function.
- Go to Banking.
- Under Bank and Credit Cards, select your bank account.
- Select Reviewed.
- Find your online transaction accidentally added.
- Click Undo.
From here, your transaction will go back under the For Review tab so you can match them with your existing records instead.
I'm adding a few references here for ideas in categorizing your transactions after utilizing the Undo function.
Reach out to me if you have any other questions. Thanks!
