In the future, you will want to do a Search for estimated tax payments and click on the jump-to link (Mac user must find estimated tax payments in the Topics List).
After the jump you will be able to enter federal, state, and local estimated tax payments that you made during the year.
Also note that without the estimated tax payments having been entered, TurboTax may calculate a penalty for the underpayment of estimated taxes.
It's possible that the IRS will notice that you paid enough estimated taxes to prevent any penalty and send you a letter. What I would do is get the transcript periodically as Mike said to see if your account had the underpayment penalty reduced or removed.
Eventually, if nothing happens, you may want to file an amended return, to get the underpayment penalty (if any) refunded.
