Not sure what you are talking about ... but if you used a paid version of the 2018 online program AND  you paid the fee already then access to your return PDF is free until 10/15/2020.

That was probably the 2019 program if you were on the Advantage program ... 

See this TurboTax support FAQ on when to expect your Advantage order - https://ttlc.intuit.com/community/choosing-a-product/help/when-can-i-expect-to-receive-my-turbotax-a...

If you no longer want the program in advance ... 

First, here's to stop your Advantage membership (annual subscription):

yes, probably 2019 for Advantage; I was charged for my 2019 TT yesterday

there have been multiple emails over the last month communicating this would occur. 

The charge for 2019 Advantage Desktop program or any program would only be on a credit card.  

Did you file 2018 late and are expecting a refund?  Have you got your refund yet?  Did you have the Turbo Tax fees deducted from your refund?  If the IRS is taking too long to send it or adjusts it you still have to pay the fees.

And see why you got charged,

Or did you use a bank debit card to pay for product in an Advantage account?  If so, that will come out of a checking account.
