Premier is not a free version of the software. In fact, "Premier" is the name of a version of the desktop download. Do you mean Premium? Premium is a paid version of online software. The only "free" offer I am aware of to use that for free would be the one to use the mobile app before 2-28. Did you use that offer---and start from the offer page?
SPECIAL OFFER FOR MOBILE APP IF YOU FILE BY 2-28

NOTE: You must start from the offer page to use this offer and you must use only the mobile app
No one in the user forum can resolve a billing issue. If you have a question about your TurboTax fees or billing, make sure you use the word “billing” in your request for help. Do not use the word “refund.”
