Credit 26AS but not received In bank account

You will have to get it rectified from your bank. (If it pertains to your bank). Give return complaint to bank first.

If bank justify it correctness, then you will be liable to declare it in ITR.

1. There may be instances where the amount could have been reflected in 26AS but the same may not be credited in a bank account. This is because of the concept of accrual. Your interest only gets accrued but not yet due for payment. Only if it's due the same will be credited in your bank account. 
2. With respect to ITR, you have two option to account your income. You can either tax your income on a cash basis or on an accural basis. If you decide to tax your income based on a cash basis, the above interest can be shown in ITR in the year in which your interest income gets credited in your bank account. If you decide to tax your income based on the accural basis, it can be shown as soon as it gets accrued, like in this case. However, you are free to follow whichever accounting method that is convenient for you. 
3. I would suggest that you show your interest income on the accrual basis that is in the current year itself. Because TDS was already deducted for the above interest income, in order to avoid mismatch of Income and TDS, it is better to show your interest income to the extent for which TDS is deducted. 
4. It is better to show your interest accrued during the year in your ITR and claim the tax credit for the same. 
please correct me if the above interpretation has an alternative view.
