Refund of TDS u/s 194N

Dear Members,

My TDS has been deducted u/s 194N in P.Y. 2020-21 and I have not filed ITR of any A.Y. preceding the A.Y. in which TDS was deducted till date.

What should I do get the refund of TDS deducted?

I have only agriculture Income which is not chargeable to tax and Income from interest on savings bank a/c which is less than Maximum amount chargeable to tax.

Please Advice.
