I have a return for whom I'm entering 1099-Q's. The taxpayer is the student whom parents' 529 distributions, reflected in the 1099-Q's, are benefiting. (She is not being claimed as a dependent on parents' return.) A few of the 1099-Q's show a parent's name "FBO" of the child/taxpayer. When the ProConnect form asks me to enter the SS number, I'm entering the parent's. ("Recipient is not the designated beneficiary" box is checked.)

Then I'm getting a "Critical Diagnostic" on the SS number, saying it "must match one of the dependents in the return." But I wouldn't enter the parent in the return at all.

Obviously I can choose to ignore this diagnostic as it's not an EF diagnostic, but is this a bug? Or should I be entering the child's name (as she's the FBO) and SS number? (On the real 1099-Q, the parent's SS number is indicated.)
