you should have gotten either an acceptance or rejection e-mail. rejected and the IRS knows nothing so the payment will not come out. others have pointed out that their payments did not come out as expected. personally, I do not use Turbotax to make payments. I use IRS Direct Pay and the state taxes are also paid through its website. have never had a problem. taxes come out on the date specified and I even get to print a receipt with tracking info should something go awry. the routing number is checked for validity though it's possible to enter a valid but incorrect number (as you can in Turbotax). you have to enter your a/c number (as you can in Turbotax) twice and they must match - though here again you could enter the same number twice but be using an invalid one.
some taxpayers even use a different electronic method for the IRS - EFTPS.
