my cousin is a non resident ..staying in USA...
TDs have been deducted on her pan on sale of property located in India...

Now in order to claim Refund of TDS deducted ...she wants to file Income tax return ..for FY.2017-18..

If she files return now just for claiming tds deducted ....is there any mandatory to file returns regularly....?????
