I have self created goodwill sold in an installment sale. I've filled out form 6252, and for line 16, the installment sale gain should be reported on "schedule d or form 4797". Instructions for 6252 seem to suggest it should only flow to Schedule D (line 11) because it is a capital asset, not 1231 asset. However it is also flowing to form 4797 line 4 (section 1231 gain from installment sales). How do i stop it from flowing here too?
