How do I delete Scholarship/Grants (for all Schools)

I accidently added the amount in Scholarship/Grants (for all Schools) box but now I cannot delete it. I was planning to add 1098-T form but added the amount under Scholarship/Grants (for all Schools) . I cannot edit the amount either it doesn't give me an option. Any idea how do I make it zero or delete as it is considering as an income?
