after tax due date including extensions: you withdraw the excess amount being carried forward on Form 5329,
(or offset it with currently allowed contribution) .
Amended return(s) will be needed supplying that Form 5329 since there is a 6% penalty per year on accreting excess contributions .
Earnings stay in the Roth account.
