Filling up itr2 for ltcg 54f exemption

Land sold and LTCG used to pay installment for new flat. I will get pocession sep/14 only. But I have paid all amount and UDS registered already. In this years ITR2 its asking for details in ITEM D for exemptions under 54f.

In LTCG column I have filled the whole consideration and also show it as 54f exemption.

In Item D should I say purchased flat and it asks aquisition date,what do i say Sep/14? Will this be ok since the date will be after the filing of return.

thanks
