Thanks for posting here in the Community, Charles. 

I understand that there's a need for you to know if you'll still be able to use vouchers after deleting the subscription in Intuit Education. However, this feature isn't supported here in QuickBooks Online. No worries, I can guide you through the process. 

By saying this, I'd recommend contacting Intuit Education's support team for they have the necessary tools for this concern. This way, they'll be able to address the queries you have and provide appropriate solutions.

I've added Intuit Education's page and attached a screenshot for your visual reference so that you can contact their support team for your guidance. 

I'll be on the lookout in the comment section if you need additional assistance regarding Intuit Education's vouchers and any QuickBooks-related queries. Keep safe.
