Hello, Sherry. 

I'll clarify the details about QuickBooks' discontinuation and supportability. 

We discontinued the services for QuickBooks 2018 (all editions) last May 31st, 2021. We are still supporting QuickBooks 2019 and above until further notice. 

I take it that you have QuickBooks 2018. You can still use the program after the discontinuation date. However, updates and online services such as the Bank Feeds and payroll can no longer be used. 

More details about the discontinuation can be found here: QuickBooks Desktop service discontinuation policy and upgrade information.

If you're received an email that wants to click on unknown links or websites (regarding the incorrect discontinuation details), I'd recommend disregarding it to protect your account.

If you're interested to upgrade to a newer version of QuickBooks, you can check this article for details on the process: Upgrade to newer versions of QuickBooks Desktop Pro Plus, Premier Plus, or Enterprise.
