Hi there, @carlos4.

I have just the steps you'll need to hide entries for any years that you've already closed. QuickBooks Online offers a plethora of awesome Filter tools that allow you to narrow sets of information in many different ways. I'll guide you through doing this below:

Filtering a List in QuickBooks Online

1. Begin by navigating to the entry list that you need to filter. In the example video below, I filter the list of all Customer Invoices.
2. Search for the Filter ▼ menu and click it. On certain screens, this is represented by a Funnel icon.
3. In the Date menu, select either This year or This year-to-date and click Apply.

We offer additional information on this in our guide on filtering or searching for transactions in QuickBooks Online. I've included a brief video demonstration below:

With these steps, you can hide all of the past entries for closed years and analyze your data much more efficiently. Please don't hesitate to reach out to me here if there's anything else you need, I'm always around to lend a hand. Thanks for coming to the Community and take care.
