• Important tax refund query

My age is 38, I worked with a government employer  as salaried for 7 months in this financial year 2016-17, starting from April -October 2016, the rest of the period I did not get any job, and did not have any income , during the period from April to October 2016, the employer deducted Rs. 1 Lakh as my PF, so  it issued me my Form 16, in which it showed the total deductions for PF(under sec 80c), as 1 Lakh, but I had invested around 60,000, in an ELSS fund during that financial year 2016-17 itself , which comes under sec80c, now while filling online IT Return, can I show my investment in ELSS Fund apart from my 1 Lakh investment in PF so that I could get tax rebate of Rs.1.5 Lakh, which I previously had got for RS.1 lakh, as given by my employer?? After doing this, will  I get a refund from the IT Dept because previously the tax was deducted taking investment under section 80c only as Rs. 1 Lac, and now I want to get exemption for 1.5 Lakh??? Plz advice, Thankyou
