ADDENDUM:
In addition to the above suggestions, if you're using a VPN, perhaps it doesn't like the VPN connecting to that server that sends out the code. I don't know if that can happen; I don't know a lot of the tech about VPNs. Kinda just thinking out loud--throwing stuff on the wall to see if anything sticks. 😁
I would try the other things I mentioned first, since I assume if you're using a VPN you need it for security at your location, especially with something as sensitive as a tax return. Or can you hard-wire to a protected Ethernet connection?
