Overcontributed to Solo Roth 401k 2022, account value down 33%

So before I contact the administrator of the account I just am curious about how this works if I contributed $19,500 to my solo roth 401k and I need to remove it all because my modified adjusted gross income after doing taxes is close to zero.

The roth solo 401k account value has considerably less than $19,500 in it, lets say $13,000.

How do I remove the full $19,500 over contribution?

 

Thanks so much for any help
