How to claim tds on fd

Hi,

I want to claim the TDS which was deducted on my FDs last year, as my income is below the 2.5L slab since I am unemployed.

Which form do I fill for this? is it the ITR1, and is there time to fill it ? I am not aware of the deadlines. This is for FY 17-18. I think it is too late to fill the 15G/H forms at banks.

I have an eFiling account. Please advise me since I am a beginner.

Thanks
