Some past transactions are mixed into different month.

I'll help you fix your reconciliation issues, mdungog.

You'll want to check your Audit log to see if someone might have unreconciled the transactions. The audit log feature allows you to check the history of changes made to individual transactions. I'll show you how:

1. Go to Settings and select Audit Log.
2. Select Filter.
3. Use the fields on the Filter panel to choose the appropriate User, Date, or Events filter to narrow the results.
4. Select Apply.

To learn more details about this, please refer to this article: Use the audit log in QuickBooks Online.

I'm also adding this link that has detailed information on how to fix issues about  past reconciliation: Fix issues for accounts you've reconciled in the past in QuickBooks Online.

I'd appreciate it if you'd update me on how the steps work. I want to make sure this is taken care of.

You'll want to record your cash transactions in a number of different ways, depending on the nature of your business.
