and I actually tried from my friend's laptop at his place, and same result! this is frustrating, is there any alternative at this point?

no luck! This is the message I get, actually the support person already gave me desktop version for free. But I couldn't download my tax file as well. May be no...

I can download my 2019 which is 1.5 MB, but this 2020 is timing out. I tried rebooting the router with no luck. Thank you
