Hi there,
I'm happy to hear you've decided to run your business with QuickBooks Self-Employed! You'll love how much time it saves you and how easy the program is to use.
It sounds like you may have subscribed twice under the same email by mistake. In order to ensure you're not going to be billed twice again next month, you can cancel one of the duplicate accounts by following the steps listed in this article: Cancel your QuickBooks Self-Employed subscription.
Since you're only able to locate one account, it's important that our team looks into this from our end to ensure you're not cancelling the wrong company account. I'd recommend reaching out to our Self-Employed team directly by filling out this email template: Contact Us. Make sure you've selected QuickBooks Self-Employed form the product list at the top right corner of the page.
I know these agents will be able to confirm the next steps with you so you're back on track in no time. Let me know if you have any other questions for me.
Have a great day!
