I appreciate you've shared this with us, @elianeblank.
Since you haven't yet reconciled the prior month, it isn't possible to move forward with the next month's reconciliation, as the ending balance of the previous/current month will be the basis and beginning balance of the following reconciliation.
For now, I recommend waiting for the correction of your accountant to keep your books accurate. You can check this article if you encounter challenges at the end of your reconciliation: Fix issues at the end of a reconciliation.
Moreover, you can visit this article for further guidance in running reports to view different aspects of your business: Run reports in QuickBooks Online.
I'm always here to help with any other questions about reconciliation. Stay safe always.
