Retirement tax questions

I think I can guess the answer to this question.

 

if my MAGI is lets say $1,000 can I leave in $1,000 in the roth 401k and just remove the $12,000 of the $13,000 thats in the account? 

To sum it up, I contributed $19,500 but I'm only allowed to contribute $1,000. The account value has current value of $13,000 because the value decreased from the $19,500 contribution. I need to remove excess of $18,500 from an account that has a value of $13,000.
