1099-Q Beneficiary was another sibling - Box 6

Hello,

 

One child is the recipient and received a 1099-Q. The distributions were used to pay for another child's    (sibling's) tuition. The distributions do not exceed the sibling's qualified educational expenses. The issue is when I enter that the funds were used for "someone else not listed here" turbotax checks box 6 saying the recipient is not the designated beneficiary. This is true, but it's not going to match the 1099-Q because that box is not checked on the actual form. Also, I assume it will be taxable since the sibling didnt have their own 529/were not listed as a beneficiary.

 

What do i do in this case?
