shack, I am attching the screenshots. Unfortunately, I do not have the newer version of NCM ( I have v7.1.1), but I am sure you will figure out where to find that in your version.
The screenshot below is from the job properties.
"Log Job steps to ..." saves the job log at C:\Program Files (x86)\SolarWinds\Orion\NCM\Jobs
"Save results to file" saves the logs at C:\Program Files (x86)\SolarWinds\Orion\NCM\Logging with the filename specified.
