Hello ASF, You can run a reconciliation report by going to the Reports tab on the left-hand side>in the search section type in reconciliation, and select the reconciliation report. It will then list by year and you can select the dropdown to expand it so it has each month/week or period reconciled and you will see a view report on the right-hand side. That is if your accountant is using the reconcile tool function. If there is nothing showing let's know and we can go through a different option.
Hello ASF, in the banking section do the in QuickBooks balance and bank balance match and there are no items left to review?\That is usually a good indicator that the banking is been done correctly. If you want to go more in-depth you can go to accounting>chart pf accounts>account history on the bank account>select the filter(the funnel symbol on the left) and filter by the date you want to look at. It has a running balance on the side of the history with which you can check. You can also run a report from the main chart of account page by clicking on the drop-down by the account history>run report which you can amend the dates of.
If anything looks as it should not we'd recommend using the reconcile tool which can show you clearly the transactions in that period, more information here
