Hi there, chartley-chucks.

I'll provide information on why you're unable to split the sales receipt in QuickBooks Online.

When you split a transaction, you'll need to make sure that you're splitting the entries that are in the Add transaction section. That being said, you're unable to split the sales receipt if it shows Match in For Review tab. This could be the reason why you can't split a sales receipt.

If you still unable to split the entry even it's Added transactions, I suggest logging into your QBO account using a private browser. This way, you're able to verify if too much data saved in your browser is causing why you're unable to split the sales receipt into 0% and 20% VAT.

Use these keyboard shortcuts based on the browser you're using.

• For Internet Explorer of Firefox, press Ctrl + Shift + P.
• For Chrome, press Ctrl + Shift + N.
• For Safari, hold down Command + Shift + N.

If it works in incognito, I recommend clearing the cache of your regular browser. This removes the history or log of sites so you can start with a clean slate. You can check this article to see the steps: How do I clear my browser cache and temporary Internet files?. 

If the steps above didn't work, use another supported browser as alternatives.

Once done, you can go back to the Banking page and split the transactions from there. Then associate VAT codes for each category. Let me guide you through the steps:

1. In your QuickBooks Online account, click Banking from the left menu.
2. Select the appropriate bank account from the list.
3. In the For Review tab, find and select the transaction.
4. Click the Split button.
5. Select the appropriate category from the drop-down.
6. In the VAT column, specify the transactions with 20% and 0% VAT codes.
7. Split the amount of the transactions, then Save and add.

For additional information, you can click this article: Categorise and match online bank transactions in QuickBooks Online. This also provides details on how to review your transactions to avoid double entries.
