I need to ammend 2019 cryptocurrency transactions. Need to delete to re-upload the entire file. How to delete my current 2019 transactions from online Turbo Tax Premier?

I have been through many screens on the Turbo Tax 2019 Premier. I have found something that lets me unselect the uploaded transactions BUT they are still there(just unselected). I need to delete all of those from Turbo Tax 2019 Online Premier and see no way to do so. I have hundreds of transactions that needed to be included into the finalized file and reupload that to Turbo Tax 2019. How can I delete all of my Cryptocurrency transactions that are there? I do not want to just upload the changes as it will be too complex to figure out short term/long term gains across hundreds of transactions, the simplest way would be to delete everything on there and just reupload the fresh finalized file.

EDIT: After going through all of the screens and options I also am NOT able to upload from CSV, it will only let me upload manually(despite me previously uploading a CSV file and I paid for Premier so I could do this). It asks me what service I used, I select Bitcoin.Tax, then it takes me to a screen where I can only manually enter 1 transaction at a time.
