What is solution to make correction in filed gstr3b

GSTR-3B once filed, cannot be revised.

Pay (through cash) / reverse such over reported input tax credit with interest in return of subsequent month.

- Refer Circular No. 26/2017-GST, dt. 29.12.2017.

suppose if reported less in subsequent month then in future my gstr2 and input will show difference

e.g. in the month of June 18 i repored over input of Rs 10000/- and iin August 18 i reported less input of Rs 10000/- to correct my input amount then I am filing 2 month wrong GSTR3B

is it ok
