Tax liabilty on gross pension

I have recently received gross pension  in my bank account. Its above seven lacs. My bank have already deducted a  tax on it above Rs. 56000/-. I transfered it to my other bank account after they deducted that tax. Now my bank manager says I have to deposit Rs. 1Lac fdr for no futhur tax deduction in that account which doesnt have any balance. Things I want  to know are:

# how much tax liability is on it?

#Is bank even allowed to deduct the tax before me submitting it in my return and depositing the tax?

#How to go about it?

Thanks in advance.
