It can take a while for the IRS to debit the funds from your account, especially during peak filing times. Also, the money won't be debited on a weekend or government holiday. If it has been 7-10 days since your return has been accepted by the IRS and the money still hasn't been debited from your account, contact IRS e-file Payment Services at 1-888-353-4537.
As for verifying the date you specified for the debit, you'll find it on the instructions page provided by TurboTax. If you need to print the return (paper copy or PDF), please see this FAQ: How do I print a copy of my return after filing, for my own records?
