Btw when I said "delete comments that say TODO if you have completed them" I meant like the whole comment (like everything in the line after the //, not just "TODO"), but it doesn't really matter in this case so I still approved it

The reason you should delete these lines is that to TODO and what it's asking you to do is redundant because your code that addresses the todo is self explanatory. If you needed to explain it, you would add a new comment that explained what your code does
