I am similar situation where I have over-contributed nearly $1000 extra in 401K contributions in 2021 due to employer change.
Today is 8th of April and even though I will notify my employer to return the excess contribution, it may not happen by 15 April. They have 401K with Vanguard and the last date to notify Vanguard for this excess contribution was 15th March (which I missed). I called Vanguard and they are saying they cannot do anything now and suggested I talk to a tax expert.
What options do I have in turbo tax if my employer is not able to return that extra contribution, their matching contribution, and any possible income generated on that extra contribution?
