How to edit/delete rules that have been created?

Thanks for sharing your concern here in the Community forum, @iosvan2020.

There are several reasons why you can't delete the Price Rules feature. Before we go further, could you let me know which specific subscription you have? Did you create the price rules using bank rules or through the specific Price Rules feature in QuickBooks Online (QBO)?

If you're using QuickBooks Self-Employed, it's simple to edit and delete bank rules. Click on the Gear icon, select Rules, find the rule you want to delete, click the drop-down option next to it, and choose Delete.

However, if you're looking to delete a bank rule in QuickBooks Online, you can follow these steps:

1. At the gear icon select Transactions from the sidebar menu and click Bank Transactions.
2. Go to the Rules tab, then find the rule you want to remove.
3. Under the Actions column, click the drop-down arrow beside Edit. 
4. Select Delete, then choose Yes to confirm the action.

If you're still unable to see the option to delete, try clearing your cache and cookies for your browser or use another supported browser. Possible that your current browser may have a temporary issue with QuickBooks. 

Additionally, if you are referring to the QBO Price Rules feature this is available only in the QuickBooks Online Plus and Advanced subscriptions. This feature enables you to set special pricing for specific customers or apply discounts during promotions. You'll need either the Plus or Advanced subscription to access and use Price Rules.

If you have one of these subscriptions, the option to delete price rules in QBO is unavailable; however, you can inactive them. Making price rules inactive stops any automatic pricing adjustments, meaning customers who previously received special pricing will now pay standard prices. This change can impact sales and promotions, potentially reducing sales volume if discounts were a significant draw.
