Although you can prepare an amendment online, it is not
possible to e-file an amendment. The IRS does not
allow amendments to be submitted electronically; amended returns
must be mailed.
Wait
for your original return to be accepted
by the IRS before printing, signing, and mailing your amended return.
You can track your amended return 3
weeks after you mail your amendment using the
IRS tracking system. See FAQ below to
track your amended return.
