If your return included a Form 8453, you'll most likely need to send a specific form or document to the IRS, even though you've successfully e-filed your return.
See the TurboTax Help article Do I need to mail anything after I've e-filed? for additional information.
But, unless TurboTax specifically told you to send any forms to the IRS when you e-filed your return, you should be done.
All you need to do is wait and see if the IRS accepts your e-filed return. If it's rejected, please see the article How do I fix a rejected return? for guidance.
