Hello there, @Brian Keith.

Processing it manually means you can sign your checks using a pen. You can also check out one of our integrated third-party applications and find this feature to include your signature on your checks when printing. 

For more information, you can review this article: Enter and write checks in QuickBooks Online.

I've also added this article for your future tasks about assessing your business' financials especially the month-end-date is fast approaching: Reconcile an account in QuickBooks Online. This contains sub-topics such as fixing and export reconciliation reports.

You can always get back in this comment section below if you have other concerns or questions. I'd be happy to assist you further. Take care.
