Your daughter can not have e-filed an amended return with Turbotax. With Turbotax and amended return can be filed only by printing it out and mailing it to the IRS. Since it takes the IRS 4 MONTHS approximately to process a properly filed amended return, you will not be able to e-file by April 18. You will need to print your return out on paper and mail it to the IRS on or before April 18, 2017.
