While filing my GSTR 1 for the m/o Dec 18 i have by mistake mentioned wrong bill amount ,taxable amount and output tax amount of one of the bill

Bill amount mentioned as 24500 instead of 74500,resulting in lower tax liability during the month.

How can i rectify it in the subsequent return of January.
