The Health Insurance Marketplace provided me with the wrong 1095-A form. Today, I received the correct one in the mail, but I have already sent off my taxes to the IRS.

You may amend your return but Turbotax will not have that option available until some time in February. At that time you can amend.

 Sign into the account you used to file your 2016 return.  Look under Manage your Return. Please see the screen shot below.
