Schedule of Gains and Losses: Ownership boc must be checked

I used TurboTax to complete the 1040 Federal without a problem on capital gains and losses.   Doing my PA-40 (Pennsylvania), which has the same set of capital gains and losses, I am stuck.  I have every box checked, filled out with Taxpayer, Spouse or Joint.  But it keeps looping me through this edit saying "Schedule of Gains and Losses: Ownership box must be checked."  Why does it do this?  How can I get past this?
