you still can file if you are working and getting your W2 and include last year
What is your question? Every year must be filed separately so if you have income from prior years, you must file separate tax returns for each of those years using TurboTax for that year to enter the income for that year. The current online version can only be used for tax year 2016. Here is a link to access prior year TurboTax products: <a rel="nofollow" target="_blank" href="https://turbotax.intuit.com/personal-taxes/past-years-products/">https://turbotax.intuit.com/personal-taxes/past-years-products/</a>
