'React' is defined but never used in React Functional Component v 16.14 (Mastering React 16)

I keep getting a warning in my terminal that

Line 1:8: ‘React’ is defined but never used no-unused-vars

I have looked for a solution to this, javascript - ESLint with React gives `no-unused-vars` errors - Stack Overflow but it doesn’t give me the location of the file I’m supposed to change and I can’t find it … or is there an easier solution to this?
