No. You can switch from online to desktop but not from desktop to online. Now that you have switched to desktop, you need to just continue in the desktop software. Remember that your tax file will only be stored on your own hard drive---or any backup device you use like a flashdrive or external hard drive. It will not be stored in an online account.
As for whatever billing issues you have----talk to customer support regarding that.
No one in the user forum can resolve a billing issue. If you have a question about your TurboTax fees or billing, make sure you use the word “billing” in your request for help. Do not use the word “refund.”
