TurboTax does not support tax year 2015. You can use a local tax professional to assist you with the 2015 tax return. Or you can use the free federal tax return forms and schedules from this IRS website - https://apps.irs.gov/app/picklist/list/priorFormPublication.html
To complete and file a 2016 tax return using TurboTax you would need to purchase, download and install on a personal computer one of the 2016 desktop editions from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/
A 2016 tax return can only be printed and mailed, it cannot be e-filed.
