Info transferred from the prior year happens automatically when you start an online return in the same account. If the info was changed after you filed last year then it was you that corrupted the archived return. And as with all DIY projects you are ultimately required to review all entries in the return for accuracy and that includes the prior year info that was pulled thru. Now if you used the Free program both this year and last then your return must have been simple so I can only guess that the state refund or the fed AGI would have been wrong.
Now if you believe the return is incorrect then you have 3 years to amend it.
Select a tax year for specific amending instructions.
Keep in mind: You have 3 years from the date you filed your return (or 2 years after you paid the tax due, whichever is later) to file an amended return, which means you don't have to get it done by the April 15 filing deadline.
