IRS not showing record of e-filed taxes

I e-filed with Turbotax on May 6th.  I got the email that it was accepted by the IRS that same day.  I ended up owing this year and I want to pay online so I made an account on the IRS website.  But they are not showing that I owe because they are not even showing that I filed.  Yet it's almost 2 months since Turbotax sent me the tax file accepted by the IRS email.  I'm not sure about just blindly mailing a check to the IRS for something they aren't even showing. Why doesn't the IRS have any record of the filing when Turbotax is telling me it was accepted?
