her amended return must be mailed in. it can not be e-filed. for online TT, i hope she did not use your a/c because the later preparation of your return completed deleted her return. it is not retrievable. for online one return per account but the same e-mail can be used for up to 5 accounts. in addition, she can't submit her amended return until her return is fully processed - refund received or payment cashed. you should claim her. if she does not amend the IRS will get around to sending both of you a letter asking each to amend.
