How can I change the fact Sales receipts that are showing as 'services' on P&L income when I have entered them as other income accounts.

Handling your concern depends on whether you mean changing a sales receipt's item type or its linked account, Pinky.

You can edit the sales receipt's associated account by navigating to the Product and services menu. But, before doing so, let's double-check the attached Product/Service item on the sales receipt to initiate the changes accurately:
 

1. Open the sales receipt(s) in question.
2. Take note of the Product/Service item.
3. Close the page by clicking the X icon.

After that, we can now edit the item's allocated account:

1. Navigate to the Gear icon, then Product and services.
2. Locate the sales receipt's attached item on the list.
3. Click its designated Edit option under the Action column.
4. Select the appropriate Other Income type of account from the Income account dropdown.
   
5. When the Also update this account in historical transactions option appears, tick its associated Checkbox icon. It ensures the changes will also affect your previous transactions under this item.
6. Hit Save and close.
   

Once done, any transactions under this item will reflect as Other Income entries on your P&L report.

On the other hand, if you mean editing the sales receipt's item type from one service to another, you can follow these instructions instead:

1. Go to the Product and services menu.
2. Locate the sales receipt's attached item on the list.
3. Select its designated Edit button under the Action column.
4. Click the Change type option.
   
5. Choose the correct item type.
6. Hit Save and close.
