Will this score hurt me?

I’ve already submitted this to 3 schools for early admissions.

See How many colleges can you apply for early decision. - Applying to College - College Confidential Forums

If it’s early decision, only one. By applying, you’re agreeing that if you get accepted, you’ll go to their school. Kinda hard to go to two schools in the event that you get accepted to both.

will reporting this score hurt my chances at schools since Computer Science is my intended major?

I don’t think so. However, the school may not award you any credits.
