Get your taxes done using TurboTax

I am not sure what is stopping me --- I have used Turbotax for years now but this computer though is a windows 10, is pretty old and pretty full.  the Deluxe I paid for and downloaded to over half hour to down load, and now when I saved my first page it would not open so had to delete and start over.  What I need to do is get a refund for the desktop version and then pay for and use the Premium version I had started and was about done with.  Is that possible? I tried finding the site I bought it on and am not sure which one, but I did get a code. I want to delete it and want a refund -- Hours of dealing with this is to much.
