Additional income line 8z from 1099q

[corbi]

Line 8z is showing additional income “qual state tuition from 1099 Q” for $2292. I received a 1099 Q and reported a gross distribution of $91316 which was all used to pay qualified college expenses for my daughter’s tuition, room & board etc… why is TT showing a taxable additional income of $2292 if all of the distribution was used for qualifying education expenses? Thank you.
