Let's rectify the issue of your missing checks so you can reconcile your bank account, willetteak.

The checks could still be in the For review tab on your QuickBooks account. To allow them to your bank register, you'll need to either add or match them. If there are no matches available, you can add them to the correct categories. Alternatively, you can select the Match radio button in QuickBooks to locate more transactions to match. This will open a new page where you can set the date range before 2024 to find other transactions. 

If QuickBooks is unable to find a match, you can exclude the transaction from your bank feeds. You can then manually record a check by following these steps:

1. Navigate to the +New button.
2. Click Check.
3. Fill in the necessary details. Ensure to associate the check with the correct accounts.
4. Press Save and Close. 

This will add the check to your bank registers, allowing you to clear them and proceed with the reconciliation process.

Can you find the checks in the bank account register?  I've never seen outstanding, unreconciled checks not show up on the reconciliation screen.  There is a filter option on the reconciliation screen so make sure there are no filters restricting the dates of transactions.   

Thank you for your reply! Yes, I had deleted all the filters, and they were still missing from the reconciliation screen, so after freaking out about yet another change by QBO engineers I took a deep breath and went searching for the checks themselves... aaaaand found the problem - a team member had posted a JE to void them and then marked them as reconciled outside of a reconciliation process, no notes, no documentation...nothing. 🤦‍So....much ado about nothing, incorrectly coming after QBO and their engineers, when all I apparently really need to do is retrain my team on how to handle bank register transactions...and to remind myself to exhaust EVERY angle of a problem before jumping into the community boards and wasting people's time. Apologies!
