Different incomes in form 16 part b and form 26as

Hi, I have received my form 16 from my previous employer with whom I worked for 6 months in the last FY.

Now, the amount provided in the Part B of Form 16 is quite different than what is shown in the Form 26 AS. The previous employer says that Part B of Form 16 is used by Income tax department and not the Form 26AS for income.

Can anyone please confirm this?
