Cashback on Property from builder - Show or not ?

Hello,

I have purchased a commercial shop from a builder. I got a cashback from the builder around 60K and tds deduction of 6000rs is also there. SHOULD I need to show in "Income from House Property" as Self Occupied? and show 60000 as rent?

and can i claim tds as refund ?

(It's a under constrution property)

Hello I got this message in property Let out if leave it blank

""Income chargeable under the head ‘House Property’ entered is less than income from house property declared to the employer. Please re-verify."" What to do ?
