I have a question related to the need to amend tax return. Is it possible to e-file amended returns online?

If you need to amend tax return(s) that you prepared using an online program, you might be able to prepare an amended return using that program. However, the IRS doesn’t accept e-filed amended returns.

You’ll need to print and mail the amendment using Form 1040X. Before you amend a return, make sure you print your return as it was originally filed. Check that everything is the same as it was when you originally filed it. Then, proceed with the amendment using the online instructions.
