Retirement tax questions

I  originally e-filed my 1040 and received a refund which was direct deposited  into  my bank account.  I  then had to amend that return so I prepared and amended return form 1040x which showed tax owing.  I then  went back into turbo tax online and imputed on the 1040x return that I wanted amount  owing to be withdrawn by irs from my bank account.  But now I do not want the withdrawal and want to pay with check when mailing in 1040x.  How do I stop the requested withdrawal?
