TurboTax answered this earlier, hope this helps
For most tax returns, the answer is no. Our e-filing "window" for non-corporate and non-partnership returns goes from January to mid-October of the calendar year that immediately follows the tax year.
For example, tax year 2019 returns can be e-filed from January 2020 through October 2020.
After e-filing shuts down for the current tax year, we're working hard to get things ready for the upcoming tax year.
