Endless loop while trying to e-file federal return

Hi! I’m going through all the way to file the federal return, asks me to sign up for credit karma and I have done both options (return to tax home or sign up with credit karma to track refund) and my return is stuck in limbo. It’s not actually submitting my return. No confirmation email or anything. I’ve cleared cookies and cache. I’ve restarted and changed devices. SOS.
