Thank you ChristieAnn.
I've contacted QuickBooks Support team and I will be able to use my Desktop QuickBooks after 30th June 2023.
For your information I was asked to press F2 to obtain my licence and product information, this didn't work for me but pressing Ctrl1 did work.
As feedback, I'm lucky that I have a one a one time licence but I do feel Intuit should be more flexible towards small businesses and allow them to keep using their desktop versions if on-line versions aren't suitable for their business. I do accept I won't receive any more support but as I frequently travel to places with no internet access the on-line version would be no good for me.
Thanks again for your help
John
