Hi, alyson3.
I'm sad to hear that you're leaving us but I understand the situation. Once you cancel your QuickBooks Online (QBO) subscription, the data in your account will be available in a read-only access for one year from the date of cancellation.
You can check this article to learn more about canceling your subscription: Cancel your QuickBooks Online subscription.
If you have plans in reactivating in the future, feel free to read this article: How to resubscribe or reactivate QuickBooks Online.
