what if a turnover of a month is bifurcated (for flexibility of tax payment) and filed in two months of 3b return.Is it ok or can it be modified in annual return

ex: Turnover of July is Rs.600000 and instead of filing 6lakhs in July return,he filed 4lakhs in July and 2 lakhs in August.What are the consequences?
