TurboTax Deluxe 2017 cannot be opened because of a problem. Check with the developer to make sure TurboTax Deluxe works with this version of OS X."

The answer (see below) does not solve my error message from TurboTax (see above) since I was not able to connect with TurboTax Technical Support numerous times.  There are too many robot answering machines that I don't understand since it got disconnected so quickly before I answer the phone with TurboTax support.  The Intuit website has no email address where I can send my comments to TurboTax Technical Support about the error message.  I was not able to upgrade my computer operating system (OS X) at this time so I would like my money back for downloading this software and I will switch to other tax software.  I am really disappointed that I have been loyal to TurboTax for many years with no problems.  Now I am not happy with the Intuit company since they hang up on me numerous times.  Please send me a link where I can ask for a refund on this downloaded software.  Thanks!  :(
