delete form 4797

Is anyone else having trouble deleting a 4797 form? I wrongly entered the sale of my primary home as 'sale of business property'  (the gain should be tax exempt, except for a small amount of depreciation I took for renting out some rooms for a few years). I fixed the error and recorded the sale on form 8949 but now there is no way to delete the capital gain in the 'sale of business property' section. When I go to that section in the software, i have deleted all forms there yet the income still remains... any help would be appreciated!!
