Taxability on maturity of lic proceeds

Dear Sir,

 Please clarify me,

1) If TDS is deducted on maturity of LIC, then what amount of income(i.e, principal+bonus or only principal/bonus) is to be shown in Total Income, and under what Head of Income it should be shown.

2) Similarly if Pension amount received on retirement what amount is tax free i.e, Principal+Interest or only Principal/ Interest
