in case of scrutiny assessment how AO compute interest u/s 234A/B/C ?(in case of company)

It is more than what we computed earlier(by hand) and also computed by software/utility.

for example.
AY 2017-18, Due date 31.10.2017,
Tax Liability 17832650
TDS 7164225, ADV tax on each period 10L+10L+25L+40L=85L and after 15/3/17 10L. under 140A= 12.60L.

interest u/s 234B by AO = 160984.
order u/s 143(3) 12/12/2019.
