You can remove payment methods from your Payment methods list screen.

Here's how:
 

1. Use the Gear icon, then go to All lists, then Payment methods.
2. Find a payment method you'd like to remove.
3. Click its Drop-Down Arrow (▼) icon in your Action column.
4. Choose Make inactive.
5. Select Yes.

If you don't see PayPal listed as a payment method on the Payment method list, or you did and you made it inactive, but it's still showing as a payment method when recording sales receipts, I'd also recommend checking your Sales settings:
 

1. Use the Gear icon, then go to Account and settings.
2. Access your Sales tab.
3. Look for any mention of PayPal being connected to QuickBooks. If you find any settings to control the connection, you can disconnect your account.

I've also included a detailed resource about using PayPal with QuickBooks which may come in handy moving forward: Use PayPal

I'll be here to help if there's any additional questions. Have a great Tuesday!
