Welcome to this thread, @Jason159. I'll be your QuickBooks guide today.

If you have canceled your Quickbooks Online account, you'll still have read-only access to it for a year. 

To get your information, log back in and get your data so you can export data to Excel

as a reference when you file your forms manually.

Otherwise, you can no longer get any data from your closed company.

I've also added this article to know more about what's going to happen after you cancel the account: What happens to my QuickBooks Online data after I cancel?.

Keep in touch and post some more of your concerns if you have any. I'll be here to be your guide.
