I need help with Clarification on Form 1310

The forms states to check box B if you are "Court-appointed or certified personal representative (defined below) claiming a refund on Form 1040-X or Form 843." I am the court-appointed representative but I'm not filing 1040-X or Form 843. I'm just filing the original 1040. I think the IRS made a change to this form recently, but it's not updated in Turbo Tax because Turbo Tax automatically checked Box B for me. But I'm not filing 1040-X, so I think I should check Box C. Any suggestions?
