I accidentally made double payment to the IRS for my 2017 tax liability. How can I cancel the payment i made with Turbo tax?

I made payment via turbo tax auto pay (giving my routing number and account number) to make payment on April 17. Then my forgetfulness thought that I need to send a check or make payment. I went to the IRS Direct Pay website and paid the full amount again. Both payments are set to be on April 17, 2018 (not yet happen). How can i cancel the payment with Turbotax? Thanks!
