I've read about this but seem to be having a brain freeze so seeking some help here.
My March 2020 my wife made an employee deferral for the year 2019 (which is clearly permitted) in her solo 401k and miscalculated the allowed amount (that was my mistake), then two weeks later we discovered the error, and contacted Fidelity and had the excess ($3k) removed from the solo 401k, still in March 2020. We reported the correct deferral amount on the 2019 tax return by ignoring the excess.
What are the tax consequences? Are we taxed on the $3k excess deferral just as if it was a withdrawal in 2020 from a retirement account (we are age 61) -- that seems odd to me but perhaps it's the law?
We did get a 1099-R from Fidelity for the $3k stating the amount was taxable in box 2a and stating distribution code as "E" in box 7 which is EPCRS.
Other?
Thank you.
