Retirement tax questions

Thank you for your reply.

 

I did a thorough review of my 401K account for 2019 and 2020 and I have contributed within the IRS individual allowed limit and there was no employer contribution either.

 

I did have some gain on my contribution through the fund I invested in. 

 

By analysing all these numbers, I am still not able to understand how can my account fail the non-discrimination testing when contribution was not over the limit.

 

Just wondering if I am missing something or the bank made a mistake before I make any kind of adjustment in turbo tax? Any pointer will be helpful.

 

Thank you.
