@Rightfield Thanks. You can see from my edits on my post right above you that I just figured out that same idea. You just plop the SEHID you calculate on Line 1 of Form 7206, right? I'm curious what you think of the rest of what I deduced in the edits in my post above you. Did I really figure out a solution to this that's going to let me correctly figure out my optimal Traditional contribution and also file a correct return? Do you know if there's a chance the IRS will reject the e-file for some reason after we've manually filled in Form 7206, Line 1 like this?
