Can I turn off automatic categorization? When I designate an expense as 'business' or 'personal,' quickbooks automatically chooses a category and the expense disappears

Welcome to the Community, lindseybrock. I'm here to share some information about categorising transactions in QuickBooks Self-Employed.

Yes, by deleting the bank rule you created, we can disable automatic categorisation of the bank transactions. But keep in mind, If you delete a rule, you won't change any of your categorised transactions. 

If you're on an internet browser:

1. Go to the Gear ⚙ icon, then Rules.
2. Find the rule and click ▼ next to Edit and then Delete. 
3. Select Yes to confirm.

If you're using an iPhone or iPad (iOS):

1. Tap your Profile icon. Then hit Settings.
2. Click on Manage Rules.
3. Pick the rule you want remove and hit Delete Rule. 
4. Select Delete to confirm.

If you're using an Android phone or tablet:

1. Tap the ≡ menu and then Settings.
2. Click on Manage Transaction Rules.
3. Pick the rule you want to remove and hit Delete Rule. 
4. Select Delete to confirm.

Furthermore, if you want to edit or recategorise the past transactions, see this article for the detailed steps: Categorise transactions in QuickBooks Self-Employed.
