It's great that you're planning ahead and know what you want to do. English is a good major to pursue if you're interested in this career, but it can also be very broad. As you plan your courses at college, you'll want to make sure you choose some electives that will help you specifically in editing. Take as many writing courses as you can within your English major, but you'll also want to be able to interpret and understand what you are editing. What type of editing do you want to do? If you think you'll be editing textbooks, you may want to also take some courses in those subjects. Medical texts (biology, microbiology, anatomy) for example, will have lots of jargon specific to that field so having a base knowledge of those subjects will also help you.
Being a planner myself, I do suggest being open to life happening to you that may change your path. I went to school for English education and assumed that I would teach public school for 35 years in the same school, then retire! That just didn't happen - now I work with international students at the college level and I really love it. As you have various experiences, make sure you're open to changing your plan. Good luck!

- If you aren't already a college student, take a look at a university website and check course plans for what courses an English, Journalism or Communications major has to take and see what appeals to you.
