For this sale, I had 1/3 ownership of the home. When I enter the #'s for 'Net Proceed' as well as the 'Cost Basis', would I divide both 'Sale price less selling expenses' (line 15 on IT-2663) and 'Cost or adjusted basis' (line 16 on IT-2663) by 3?
The estimated tax that I paid to NY was based on 1/3 ownership. i.e. on line 18 of IT-2663, I followed the instructions for "two or more persons transfer or sell the real property..." and divided the total gain by 3.
