UTMA Gains Adjustment Code N

I am filing for my grandson who has a UTMA account.

 

I downloaded the 1099 from Etrade.   

 

Turbotax is showing "adjustment code N" on all the trades, as shown on the 1099B worksheet.  I think this is incorrect.

 

Should I override the N, or put in zero as the adjustment amount, or do something else?

 

Thanks

 

PS the 1099 document itself does not show an adjustment code so I wonder if this is a bug?
