Let me help you fix this reconciliation issue, Ijsamuel.
We'll have to ensure the transactions you split are reconciled as well. This way, you'll not encounter any issues for the new month. Here's how:
- Click Accounting.
- Go to the Chart of Accounts tab.
- Select the bank account, then click View register.
- Look for the transactions and check if you can see R in the column between Deposit and Balance.
If you're unable to see the R status, it means the transaction isn't reconciled. Click on the blank field until you reached R, then click Save.
Once done, try to reconcile the new month and check if there are any other issues. If there are any discrepancies, you can check this article to help you fix them: Fix issues for accounts you've reconciled in the past in QuickBooks Online.
