How to generate 6252 for S Corp sale of Goodwill in Lacerte? I tried entering in screen 23, but when I try to click 6252 option for current year installment sale it won't let me click it. It won't let me enter data anywhere in Screen 23 except the Schedule D sale price and costs and dates. How to I get Form 6252 to generate. I read the online instructions and they were not helpful.
