I enter on a Sch A worksheet and it flows over to the Form 8283.   I am unable to enter direct on Form 8283 and in fact the  program states "Do not enter info directly on Form 8283". The Form 8283 does have a X beside the box for Qualified Conservation Contribution so at first glance I think I have entered it in correctly but am confused why the program is limiting donation to 30% of AGI and not 50%.
