I had excess contribution of 401k in 2018 due to miscalculation when switching job. I have requested our HR department to contact the retirement account manager to withdraw the amount of excess contribution. But current haven't received confirmation about whether this can be done before April 15. Shall I still report it as 1099-R items? What else needs to be reported other than the amount of excess contribution? Shall I select 8 - Return of contribution taxable in 2018 in box 7? Please advice, thanks!
