TurboTax does not support tax years prior to 2016.
You can either go to a tax professional in your local area for assistance or use the IRS website for prior year federal tax forms, schedules and instructions - https://apps.irs.gov/app/picklist/list/priorFormPublication.html
To complete prior year tax returns, 2016 thru 2018, using TurboTax you will need to purchase, download and install on a personal computer one of the desktop editions for each tax year required from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/
Prior year tax returns can only be printed and mailed, they cannot be e-filed. Use separate envelopes for each tax year when mailing the tax returns.
