We closed our business last year

Welcome to the QuickBooks Community, @Cathy_Jo.

May I know additional details of your concern? Any information will be a great help so I can give you a timely solution. In the meantime, let me share some info about what happens when you closed your business and if you've cancelled your QuickBooks Online (QBO) subscription. 

Once your QBO account is cancelled, you'll only be given read-only access to your accounting data for a year. To have a copy of your data, you can export them and save them on your hard drive. When the period ends, the system will automatically delete your account. Check out this link for more details: What happens to my QuickBooks Online data after I cancel?

I've also added this helpful page for additional reference: Close business and finish payroll tasks.

Community articles are also a great help to guide you with your QuickBooks tasks. You can either save them or bookmark them for future use. To do so, just type the keyword of your concern in the search bar or select any of the categories displayed. 

Keep me posted if you need further assistance about your closed business. I'll be on the lookout for your response. Take care always.
