After the IRS page confirmed my refund would go to my bank after taking owed. How do I know which account will the remainder go into now, my original account?

I filed and I owed then IRS a portion of my check, originally I e-filed thru Turbo Tax and was dividing my tax return into 2 accounts.   The IRS page confirmed the remainder would go to my bank account by the 17th, so how do I know which account will it be deposited into?   Will it be my original account?
