When you say you signed up, did you open a new TurboTax Advantage account? Or did you simply sign into your TurboTax account (not Advantage) and download the new 2020 product?
TurboTax Advantage is the auto-renew program, ensuring that you'll always receive the TurboTax product of your choice each year without ordering it again. If you already have a TurboTax Advantage account (from Dec., 2017?), it may be under a different login. You can cancel that TurboTax Advantage account (use the same login that you originally signed up with) by following the instructions included in the TurboTax FAQ linked below.
How do I cancel my TurboTax Advantage subscription?
If you won't be charged until November, 2021, that indicates that your purchase is for next year's product (2021).
If you continue to have difficulty, please contact TurboTax Customer Support during regular business hours. Use the info linked below to contact Support.
