I'm using TTax Premier 2021 CD Windows 10. I receive the internet transmission error referencing Intuit's Electronic Filing Center when I try to file my returns. I've received this error for the past three days even after updating TTax, uninstalling TTax, reinstalling and also rebooting. Nothing works! "Make sure your modem and phones are connected"??? If I was having modem problems I couldn't update TTax. I can update TTax. Any suggestions?
