Did you go to the EFTPS and pay it yourself and then put down the bank info on your tax return so the IRS pulled it again? And they both have the same description on your bank statement? Guess you better call the IRS 1-800-829-1040. If you paid it yourself using EFTPS maybe you put it down as a 2015 Estimated tax payment instead of a 2014 tax due payment.
I would also get a copy of your account from the IRS and see if it shows twice.
