Tds on epf withdrawal

Hi,

I was a resident until Nov'16 after which I got a job abroad in Jul'17 and have currently settled there. I withdrew my complete EPF in Feb'18 as I had to close it once becoming a NRI and TDS of 10% was deducted. I'm planning to file IT return for AY 17-18. My doubt is:

* Is my EPF withdrawal considered income from slaary for AY 17-18? My EPF withdrawal amount was ~4.5 lakhs. What is the taxation on my EPF withdrawal? Can I refund the TDS deducted for any extra tax paid? I don't own any other assets or have any other income in India for AY 17-18.

Thanks in advance.
