No, it's not. I had sale of residence converted to a rental earlier in the season. I had converted the rental to personal use (they stopped renting, knew they were selling), and I have a feeling that might help you. I entered the whole kit and caboodle on the Sale of Personal Residence tab.
In general, (any reporting of a sale of residence on that tab), I don't know why ATX won't account for sales commissions incurred on the sale, but will increase basis by sales commissions incurred on your purchase. (On the Sch D - they do show on the worksheet).
