Deductions & credits

Hi thanks.  Yes, home sale showed up on both the 8949 and Schedule D.  It's showing a gain of about $19000 but I have way more than that as capital loss carryovers.  I thought previous losses could offset current gains....not just the $3000.  Also, shouldn't the new home I purchased ( which was less than the sale price of my old home) factor in to the equation?  I did not receive a 1099-S
