Retirement tax questions

I'm confused.  All the posts I have read about excess deferrals say to enter excess deferral under "Other income not already reported on a Form W-2 or Form 1099" section because TurboTax will not automatically add the excess deferral to my wages.  Granted all the posts I can find on this topic are about excess deferrals returned prior to April 15th.  Are the steps you recommend unique to excess deferrals returned AFTER April 15th?  Thanks.
