Hello Flyingfemme, thanks for your reply. 

This is the situation. If you bought a licence for QuickBooks Desktop through a one-off payment, whether it was directly from Intuit or through a retail outlet like Staples or Curry's, you'll still have access to your account after June 30, 2023.

However, starting from April 7, 2024, you won't be able to submit MTD reports to HMRC. As stated in this article.
