Trying to reconcile; I see transactions from '21 showing in bank register as C instead of R which I think is the issue. How can I change w/o changing completed reconcili?

Hello, @dodgetreasurer@g.

When a bank transaction originates from your bank directly, the Cleared (C) status is displayed. QuickBooks, therefore, marks transactions as "C" when you download or import and accept them. This means they're ready to be reconciled. On the other hand, the Reconciled (R) status shows that these items correspond to your bank statement.

In your case, you might've edited or changed the wrong transaction. I recommend checking your bank statement to ensure you're reconciling the correct account.

Moving forward, I suggest not changing the status unless it's for the current reconciliation period to avoid your end/opening balance being affected. You can also get bank statements directly from your bank to make sure everything matches.

I've also added an article here that you can read through to help you fix reconciliation issues: Fix issues for accounts you've reconciled in the past in QuickBooks Online. 

Should you need anything else with your bank transactions, I'm just a reply away. Have a great day!
