8379 Injured Spouse Form
I efiled a 1040 tax return for 2017 for a couple, MFJ. They spouse has a lien from Social Security filed with the IRS which has existed for some time. In prior years, I filed a Form 8379 "Injured Spouse Claim" but I did not attach an 8379 for 2017 to their joint return. Can I submit an 8379 for 2017 electronically through a 1040X, with no changes to the 2017 tax return other than the 8379 form?
