I removed the original dependent in the info works and added the correct one. On page two it lists the correct (new) dependent I added. I did fill out the explanation. My error detail reads: If Form 1040X 'total payments less overpayment amount' is not equal to total tax amount in correct number or amount group then at least one of the following must have a non zero value, [owed amount or net overpayment amount or refund amount or applied estimate amount]
