Tds salary paid adjustment

SUPPOSE, In quarter 2, an employee got paid 100,000 and the respective tax amount got deducted via tds but due clerical negligance, taxable amount got reported as 50,000 in Q2 returns.

This error got discovered only after filling for fourth quarter. What is the procedure to fix this?

Instead of revising returns on Q 2, can I revise Q4 and add the remaining un reported 50k by addinf it to the salary amount?

PLEASE helo me here.
