You cannot open an old tax rerun by clicking on it. You must first start and run TurboTax and the use the File -> Open Tax Return then locate and select the data file for that year for it to open.
Note that 2014 & 2015 is no longer supported by TurboTax and will not run on OSX 10.13.4 or later without running a "fix script" first but that script is no longer available.
