Good day, organicinvestmen. I would like to help you find where the 2019 transactions are.
If you haven't matched the 2019 transactions yet, we can select the Last Year option from the Date field. It's a way to see these transactions on the lists. Let me guide you how:
Go to Banking and select the Banking tab.
In the For Review section, click the Funnel icon next to the Batch action button.
Click the drop-down arrow for the date and select Last Year.
On the other hand, if these transactions have been reviewed or exuded, it will no longer appear on the for review tab. You'll want to check out the article about matching and categorizing bank transactions. Also, you can visit here on how to remove transactions about reviewing them in your book.
I'm always here whenever you need help with QuickBooks Online. Take care!
