I ended up choosing to use a tax preparer & filed with them. TurboTax won't let me clear those files from this year & close my account with them. How can I do that ?

I filed with a preparer that I got through a friend's reccomedation, was notified of what my refund exact  amount will be and recieved notice that is currentlybeing processed (3x more than what they offered under the free tax filing option with TurboTax) and the TurboTax app and website claim I cannot clear my info or close my account because of my "active" tax files with them (that I never continued to file with them and finish the process) & is only giving me the option to continue to filing, not even remove any information they already have from me. I worry that they will try to file without my consent and mess up my current processing refund with that bs.
