In tax year 2018 I over-contributed to my 401k due to job change. Although I discovered the problem before the tax return filing deadline, the bank refused to return the excess funds.
I've consulted a CPA and we filed the tax return.
The next year I made sure to contribute less to my 401k, so that the 2019 contributions + excess 2018 contributions are within limits. (Maybe it was wrong to do...)
The question is: What do I need to do for tax return for 2019 to "close" the issue? Do I need to put my last year's excess anywhere?
Unlike excess HSA contributions, I do not see any special effect of the 401k excess in the tax return forms.
P.S. Did I just make a mistake to limit my 2019 401k contributions?
