How do you cancel a self employed subscription? the menu will not allow me to cancel, it brings up a pop up every time

It depends on where you bought your subscription from @jenn-practicalfa.

It only takes a few easy steps to cancel your QuickBooks Self-Employed (QBSE) subscription. Before that, can you tell me what’s indicated on the pop-up?

If you bought QBSE directly from QuickBooks or Intuit, follow these steps below: 

1. Sign in to QuickBooks Self-Employed in a web browser.
2. Select the Gear icon.
3. Choose Billing Info and then Cancel subscription.
   

On the other hand, if you bought it through the mobile app store, you can refer to this article here for a step-by-step process to cancel your subscription.

QuickBooks keep your data for one year from the date of cancellation. However, you’re unable to modify your entries nor delete them. Meaning, files are for read-only access afterward. In case you need them for future purposes, I recommend exporting and save them. 

Let me know if you need further assistance with canceling your account. I’m here always to lend a hand. Always take care.

Thanks, @MadelynC

This is what the pop up says:

Wait, don't go!
