OK. Let’s review your question. Here’s what I’ve got:<br><br>"Has anyone had 2020 transactions suddenly popping up now to review? If so anyone know why?

Thanks for letting us know of your concern, @tianaslunchbox-y. As an insight, QuickBooks depends on the transactions shared by your bank.

You'll want to exclude these transactions so QuickBooks will ignore them. Here's how: 

1. Go to the Transactions menu, then search the transaction you want to exclude and select it to expand the view.
2. Select the Exclude this transaction checkbox.
3. Select Save.
