May I ask what you are using to complete 2013 returns right now? They can't be done online since it's for current tax year of 2017 only and TurboTax no longer sells nor supports the 2013 CD/Download software. See below for your options on filing a 2013 return.
Can I use TurboTax to file a 2013, 2012, 2011, or earlier tax return?
