Amended Returns - Prior Years

[Burke]

In order for the tax to calculate correctly, I have to use prior year's software to amend return. Those years did not have new 1040X form. Do I have to use new form? This means manually processing to print in this year's software.

Update

When I update my prior year software, one of the updates is the new 1040X form. Try updating before preparing an amended return.

Duh. Why didn't I think of that?

My understanding is that the IRS will accept either the one column or the three column version of the 1040X for open tax years.
