If you used the ONLINE version instead of the Downloaded one then that program would have asked for the CC information in the FILE tab and at that point you should have questioned it and posted a question so this matter could have been corrected before you paid a second time. Now your only recourse is to contact TT support to get a refund of the duplicated payment.
The alternate way was to download the program if the CD install was not working and not to use the ONLINE version ... that is where you made your error. Now make sure you save the PDF and the .taxfile of the 2020 return so you have the information on your computer and the .taxfile to transfer into the next year's program if you choose to go back to the Downloaded version again.
