After you file

here's how it works.

You tell the custodian what you want to do.

the custodian calculates your earnings on that $6,000 plus or minus and moves the result so adjusted.

 

meanwhile you report on your tax return the original amount you put in as having been removed.

 

Too late now since you already had something done.

Call custodian to determine if your action was treated as a removal of excess as I describe.
