You only would have been asked to pay for the service once you completed the tax return and were in the File section of the program on Step 1 and then only after you reviewed your order showing the amount of the account fees.
If for some reason you still paid for the account using a credit card then you will need to contact TurboTax support to see if you can get a refund for the account fees. Use the key words Billing Issue when contacting support.
See this TurboTax support FAQ for contacting support - https://ttlc.intuit.com/turbotax-support/en-us/help-article/account-management/turbotax-phone-number...
