How do I turn internship tasks into results on my resume?

Ask "what happened because I did this?" for each task, then add that outcome to the bullet. Results can be time saved, errors found, people helped, documents delivered or decisions supported.

Examples:

• Task: "Updated the customer database."
• Result: "Updated 1,200 customer records, removing duplicates before a marketing email campaign."

• Task: "Did research on competitors."
• Result: "Researched pricing for six competitors; findings used in the team's quarterly pricing review."

If you do not know the final outcome, describe the output and who used it. Never invent results you cannot confirm.

A useful habit is to keep a short weekly log during any internship: what you worked on, who used it and any feedback you received. At the end, you will have plenty of real material for your resume, and you can ask your supervisor about outcomes before you leave, while the details are still fresh.
