If you log back into TurboTax Online, you should be able to download a printable PDF copy of your return. You may have to go to My TurboTax > My Tax Timeline to get the download link.
Please note that FAFSA rules have changed. If you're applying for 2017-18 financial aid, they now want your 2015 tax return (prepared last tax season), *NOT* your 2016 return as in past years.
