If you received a corrected tax form after filing (the "corrected" box is checked) and the new info changes your refund or tax due amount, you will need to amend your return. You may need to go through the amend process to determine if that is the case for your personal tax situation. Please see the following TurboTax FAQ for instructions on how to amend your 2016 tax
return in TurboTax.
