Filing it returns for lic agent cum salaried income

Dear Sir,
I am LIC agent as well as a salaried employee. My main source of income is from my salary. But I get more income from my commission from LIC. 
My salary income shown in form 16 is rs 4,47320. Since my company is filing first time tds. In traces it shows only 68k as income and tax deducted is 1790. 
My Commission income from LIC is rs.2,60,000 tax deducted is 16k.

My doubt is..
1.shud I file returns in ITR 1 Or ITR 4.
2. shud I mention income as it is in form 16 or leave as it is shown in traces?

How can I file the return for both at a time, Shall I file the both in ITR 1 or should I file in ITR 1 and ITR4.

KINDLY suggest me the idea

Regards
