How can a F1 student who used TurboTax for the past 4 years, file amendments now for the years older than 3 years ago?

How do I file amendments for earlier years than 2017? Down to 2014.

TurboTax does not support tax year 2014.  A 2014 tax return or amended tax return for tax year 2014 with a tax refund had to be filed on or before April 15, 2018.

See this TurboTax support FAQ for amending a tax return - https://ttlc.intuit.com/questions/1894381-how-to-amend-change-or-correct-a-return-you-already-filed

Ok thanks, but the question is asking what to do about the amendments that were not filed on time.

For a 2014 federal amended tax return, form 1040X or earlier, go to the IRS website for free forms, schedules and instructions.  The website has all prior year tax forms -  <a rel="nofollow" target="_blank" href="https://apps.irs.gov/app/picklist/list/priorFormPublication.html">https://apps.irs.gov/app/picklist/...>
