Retirement tax questions

I am in the same boat as bareli as extra payout made me not eligible to contribute to my ROTH IRA but both my wife and I have contributed $7000 each at the beginning of the year.   I also contributed $7,000 for 2021.   Now I need to remove $21,000 from our accounts.   I am trying to contact Charles Schwab to initiate withdrawal.  What other  steps should I do now?  Please advise.
