Did you use the current online version to enter your 2015 info?  Online is only for 2016 returns.  So you might have a problem.  You didn't actually efile it did you?  Better check if you did and if it went through.      <a rel="nofollow" target="_blank" href="https://turbotax.intuit.com/tax-tools/efile-status-lookup/">https://turbotax.intuit.com/tax-tools/ef...>

If it was Accepted, post back, you will need to fix it.

The TurboTax online editions are only for tax year 2016.

To complete and file a tax year 2015 tax return you will need to purchase and download one of the 2015 desktop editions from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/

A 2015 tax return can only be printed and mailed, it cannot be e-filed.

However, if you started a 2015 tax return using the online editions for tax year 2015 (during calendar year 2016) then see this TurboTax support FAQ for completing the prior year tax return - https://ttlc.intuit.com/questions/2559403-how-do-i-finish-a-prior-year-return-that-i-started-in-turb...

You have to sign onto your 2015 online account using the exact same user ID you used to create the account.

Close all TurboTax windows on your web browser (including this one).  Copy and paste the account recovery website link onto a new web browser window and run the tool.

Use this TurboTax account recovery website to get a list of all the user ID's for an email address.  Run the tool against any email addresses you may have used - https://myturbotax.intuit.com/account-recovery

If none of the user ID's received will access your 2015 account, then use the option shown in blue on the account recovery website, "Try something else"
