Where do I enter contributions to a 529 education account on the Virginia state return. Responses from turbotax/ answerXchange didn't help. Form VAC isn't in library.

I looked for the recommended screens from the turbotax/answerX change --- "Do you have any personal adjustments" and "Here's the income that Virginia handles differently".  Did not find either one.  They also recommended Form "VAC" which isn't in the library.  Any suggestions?
