TT Premier Desktop 2022 Bug - won't allow amended return if tax owed did not change

I'm filing for my newlywed kids who only earned $13K last year. Taxes already filed and accepted already via TT Premier Desktop 2022.

 

My son in law forgot to give me a 1099 showing $7K in trading losses.

I entered the 1099 fine, no change in their refund amount, but there is no option anywhere to do an amended return!!

 

I think this is a bug, please advise asap.
