44ADA income declaration

In my previous year ITR where I declared income u/s 44ADA, I have mistakenly declared 100% of turnover as income. Will there be any problem if I choose to declare 50% of my turnover as income in my current year ITR. Like is there any chance for scrutiny notice or anything as books of accounts need not be maintenaned under this section. Amts are not huge, tax difference comes below 10k due to this.
