Can you confirm that it was accepted and that Where's My Refund shows it being processed? Here is a link to a thread that details how to go through the automated phone prompts to reach a live representative. The steps may save you some frustration. You can also search for a local IRS office in your area. It may be easier to contact a local representative than using the main phone number. You can use the ''make an appointment'' option even if you have no intention of going to the office, but that may get you a live person on the phone that can provide you some info. They have access to the same information.
The IRS issues refunds, not TurboTax. This means that we can't say for sure why you haven’t received your refund if it's been longer than 21 days since you e-filed. You'll have to speak directly to IRS to find out more about the delay.
