Where do you deduct closing costs for new home purchases?

Mostly they are not deductible.

There should be a place under mortgage interest to deduct points, if paid by either buyer or seller.  I don't use ProConnect, so I'm not sure.  In many locations the buyer gets a credit for property taxes pro-rated to the seller up until closing date, so be sure to subtract that from any taxes paid by the buyer.
