Yes, if you claimed the wrong filing status, you will need to amend that return and change to the correct filing status.
NOTE: Amended returns will need to be printed and mailed since they cannot be e-filed. They can take up to 16 weeks to be processed. If you did not file your 2015 return with TurboTax, you can go here on the IRS website https://www.irs.gov/forms-pubs and print the 2015 forms to complete and mail.
