Hello Aspirant,

No, it cannot be corrected. See all fields are not editable only some fields can be edited like some personal details, academic qualification details, choice of examination center, category and some other but don't worry here your income does not matter until and unless you belongs to OBC-NCL or EWS category, even if you belongs to any of the aforesaid category then also you can later submit your income certificate as your income proof so it will not create any issue.

I hope this information helps you.

Good Luck!!
