Hello @bookkeeper by heart,
Let me help share information about how you can reconcile your bank account for a month worth of transactions.
To start with, you go ahead and reconcile the split transaction as long as the amount and category (each line item) match with what is stated on your bank statement. But if not, you can consider deleting the split transaction and recreate it base on every category used in each line item.
That being said, here's an article you can read to learn more about the reconciliation workflow: How to reconcile your accounts so they always match your bank and credit card statements?
Additionally, I've also included this helpful article for the troubleshooting steps in case you'll bump into issues with reconciliation: What to do QuickBooks Online doesn't match your bank statement at the end of a reconciliation?
If there's anything else that I can help you with, please let me know by leaving any comments below. I'll be here to lend a helping hand.
