Thank you - that's what I thought.
The reason that the personal elective deferral and catch up contribution were not reported on my W-2 is that I choose to fund the Solo 401K at the end of the year in one lump sum.
The S corp must deposit your elective deferrals made from your pay. Your lump-sum elective deferral at year-end is only permitted if the election to make an elective deferral was made by year-end, the S corp withheld the amount of the elective deferral from your last paycheck of the year and the S corp deposited it into the 401(k). The S corp must then report the elective deferral with code D in box 12 of your W-2.
