Your amended return is not filed until you mail it in. You cannot e-file an amended return. They have to be
mailed, and it takes
up to 16 weeks for the IRS to process an amended return. 3 weeks after you
mailed your amendment, you can start tracking its progress at the IRS Where's My Amended
Return? site.
Instructions to amend can be found here. Please review them to be sure you have done the amendment process correctly: https://ttlc.intuit.com/replies/5567856
