Welcome to the QuickBooks Community, Stacy.
Before proceeding, can you clarify why payments for different invoices were combined into one transaction? Any additional details would be helpful.
Meanwhile, there are a few ways to manage the combined transactions without splitting them so you can reconcile last month’s records. The first option is to delete the combined payment for the ACH and check, then manually record the ACH payment. Once the check clears, record it separately and ensure to assign the correct payment method for each transaction.
You’ll also need to manually calculate the ending balance to ensure each month’s transactions are reconciled accurately. Be sure to select only the transactions that appear on your bank statement. After completing these steps, you can finalize your reconciliation.
Another option is to wait until the check clears before reconciling. If you prefer not to record separate payments, you can reconcile both months’ records together once the check has cleared.
For additional guidance, consider consulting an accountant during this process. You can refer to this link on how to find one: https://quickbooks.intuit.com/find-an-accountant/.
