Short deduction notice by cpc

I have received TDS short deduction notice from the CPC for 24Q quarter 4 returns. however tds short deducted was paid by the employee concerned later. My question is what should I do to resolve the default? Because there is no error in the return for which i have to file correction statement. Further, now a days notices are issued electronically by CPC. So if i have to communicate this to department, how can i do this?? please help.
