Are you looking for landing pages on your own site? If so, Google Search Console is your best bet. Go to Search Analytics, click on the query you're interested in, and Google will show you all of your site's pages that have ranked for that term within the last 90 days, along with their impressions and clicks.
Moz and most ranking trackers will also show this. You can go to your campaign in your Moz Pro account and choose Analyze Keyword under rankings. Choose a keyword and scroll to the bottom to see a list of what ranks for the first 5 pages on Google.
Does this help? Do you know which keywords you think you might be ranking for multiple times, or are you trying to find those keywords?
Best,
