Filed taxes twice what should I do?

If you e-filed a tax return using TurboTax then you cannot e-file another tax return with your Social Security number, as it will be rejected.

If you e-filed a tax return using TurboTax, you generally can't e-file another return using the same Social Security number for the same tax year because the IRS system will reject it.

If you filed two different returns for two separate tax years, you should keep those filings separate as each tax year requires its own return on the correct form.
