Youn owe TurboTax fees. If you didn't get a refund - then you still owe Turbotax fees.
You apparently chose to pay your TurboTax fees out of the Federal refund, and your Federal refund must not have been forthcoming yet at this point in time or was reduced by the IRS. When TurboTax sends out a billing email, here are a couple of possibilities that can trigger that:
1) Either the IRS reduced the amount of your Federal refund such that it would no longer cover the TurboTax fees,
OR
2) Your refund has simply been delayed at the IRS. If it's taking the IRS a long time to process your refund--for whatever reason--TurboTax will want payment if it goes 36 days past your original estimated refund date.
You can check the status at the IRS "Where's My Refund" site to see if the IRS has released the refund, or whether it's delayed, and if they are still processing it.
Pay attention to the billing emails you receive from TurboTax. If you don't pay or contact Customer Support to request a deferment, they will eventually send you an email saying that they are about to debit your bank account. If you still don't respond, then they will debit your bank account.
If you can't pay it right now, contact Customer Support and request a deferment so they won't debit your bank account.
FAQ: What is the TurboTax phone number?
https://ttlc.intuit.com/questions/1899263
If that "Where's My Refund" tool above says your return is still being processed, you can phone and speak to a live IRS agent on Monday to see if you can learn anything about the delay. Here's how to wade through their phone system:
IRS: 800-829-1040 hours 7 AM - 7 PM local time Mon-Fri
Listen to each menu before making the selection.
First choose your language. Press 1 for English.
Then do NOT choose the first choice re: "Refund", or it will send you to an automated phone line.
Instead, press 2 for "personal income tax".
Then press 1 for "form, tax history, or payment".
Then press 3 "for all other questions."
Then press 2 "for all other questions." It should then transfer you to an agent, but there is likely to be a long wait.
I usually use a speakerphone so I can work on something else while waiting.
