Unable to claim Deduction in ITR 2 u/s 80 CCD(2)

Yes, a deduction under Section 80CCD(2) is available even if you opt for the new tax regime. Check the questionnaire, you have to tick 'YES' to it.

Under schedule VI-A Part B when amount entered in 80CCD(2) the eligible amount relflects as zero, can anyone help?

It has to be enabled from schedule 'General' under Tab Deductions.

Thanks, when salary break up details provided under income it got enabled under chapter VI-A by default. 

If the value reflects zero, such exercises are mandatory.

I too have same problem. Couldn't find the check box for 80CCD(2) in deductions. Please suggest.
