Hi, @More Frustrated. Allow me to share with you some information about the Check Mark (✓) column on the Bank Reconciliation window.

The Check Mark column is designed smaller than other fields just to fit the ✓ when reconciling your transactions. Expanding the column is currently unavailable.

I can see the importance of resetting the size on this column. I'll take note of your feedback about this field and pass it along to our product developers. Rest assured their working nonstop to enhance the product and deliver the best experiences for all QuickBooks users.

For the time being, you can proceed with reconciling your accounts. You can use this article as your guide: Reconcile an account in QuickBooks Desktop.

Just in case you encounter issues with the balances, you can review the steps from this link to fix the issue: Reconcile previously deleted and re-entered checking or credit card transactions.

Please let me know if you have any other questions while reconciling your account. I'm always here to help. Keep safe!
