Double Charge?

I just signed up and download 2020 program; now I get a notice aboutTurbo Tax Advantage enrollment dated Dec. 12, 2017 for $100. under my Visa card 6016.  Says I won't be charged until November 2021.  Is this just from a past T.T. Advantage sign up?  I only need one program for 2020 tax return.  Make sure I only get charged one time for $100.  My home phone [phone number removed] has a recorder, call me and leave message if I do not answer or email me at:  [email address removed]

Thanks
