Started an subscription. QB created new business but I've been working on existing one. Need to remove Other businesses and ensure subscription applied to correct one.

Hello connect-sumaneat, 

Thanks for messaging us here. QuickBooks is designed to help make your work easier using the features offered in the program. Rest assured, I'll be happy to help from here. 

To get started, you'd have to cancel the unwanted  account since you'd like to continue using the already existing one. Here's an article that provides more info about canceling an account: https://quickbooks.intuit.com/learn-support/en-ca/help-article/cancel-products-services/cancel-quick....

It's important to note that the ability to merge two subscriptions isn't available. Hence, deleting the unwanted account would be right route to take. In case there were charges applied to your card, you can simply request for a refund through this link: https://quickbooks.intuit.com/learn-support/en-ca/help-article/intuit-refunds/request-refund-quickbo.... Let me know if you have questions so far, I'm here to assist.

That worked, thank you!  I was worried it would void the subscription but all is well.

Perfect! I'm happy to hear you were able to get this resolved!
