Hello there, @stvnkrchnr!
You can add or match only one of the six bank transactions and exclude the other five.
- Go to Banking.
- Under Bank and Credit Cards, select your credit card account.
- On the For Review tab, select all the other five transactions.
- Select Batch actions.
- Click Exclude Selected.
In addition, here's an article you can read to learn more about excluding your bank transactions: Exclude expenses from downloaded bank transactions.
Lastly, I've got you this helpful article for ideas about reviewing a transaction in your bank account register: Find, review, and edit transactions in account registers.
Keep me posted in the comments if you have any other questions. I'll be here to lend a hand.
