Hi there, @Azzalee.
Thanks for hopping into this thread. The CIS feature is only offered in our Small Business products, not in Self Employed. If you'll need to use this feature, you may consider using the QuickBooks Online subscription.
Check out this attached article for our product pricing guide https://quickbooks.intuit.com/uk/pricing/.
For more details about adding contractor/sub-contractor and CIS transactions, please refer to this article: Already using CIS in QuickBooks?.
Feel free to comment below if you have more questions. We're always happy to assist.
