Form 27q submission for q1 fy 2017-18

I need to file a TDS return in Form 27Q for Q1 2017-18 regarding property sale by NRI to resident but the NSDL utility is not allowing me - it says return cannot be prepared till completion of quarter i.e. June 30, 2017

But my question is: in that case, the NRI seller will not be able to get Form 16A till return is filed. He is asking for Form 16A urgently. In such a situation, is there any other way?

The TDS has already been deposited in ITNS 281 and copy of challan given to seller but he wants Form 16A also.

Please advise. Thanks in advance.
