The IRS not processing or issuing a tax refund is not the responsibility of TurboTax.
You agreed to pay the TurboTax account fees and if the IRS delays the issuance of your federal tax refund then TurboTax can request payment of the fees you agreed to.
See this TurboTax support FAQ for payment of the account fees - https://ttlc.intuit.com/community/charges-and-fees/help/why-was-my-bank-account-auto-debited-for-turbotax-fees/01/26102
Sounds like the IRS is taking too long to send your refund or reduced it. See What if the IRS reduces your refund or delays it.

Then when the IRS does send your refund they won't take the fees out again.
And, Why you got charged,

You should have received about 4 emails asking for the fees. If you don't pay they will debit your account. You had to agree to it. Check your spam folder for emails.
