Supplement prorated tax

I purchased the house on 2/28/17 and sold it on 7/7/17. The county tax agent told me that the 2 supplement tax assessments were for before 6/30/17 and after 7/1/17-7/7/17 when I was the buyer.  Please advise these 3 questions that I asked before but did not clearly answer.
1. Should these 2 supplement taxes be on Schedule A or be added to part of my cost basis?
2. Should the prorated taxes for both purchase and selling closing statements be added in the cost basis and sales proceeds to determine the gain AND not in Schedule A (is it Yes or No)
3. Where to input the estimated amount of tax withheld for my gain of selling the property on Form 593E that was deducted from my proceeds in the closing statement. Is it in Schedule A again.
