Excess contribution to a 401k then rolled over into an IRA

[dmertz]

With the addition of mentioning the increase in your taxable income due to the $4,600 becoming taxable, your explanation seems reasonable to me, but of course I already understand the situation.

You need to amend to avoid the $4,600 being treated as an excess contribution to the IRA.  The law requires that nondeductible traditional IRA contributions be reported on your tax return, which is done on Form 8606.
