Today is Jun 2rd, 2020 -- I am having a similar problem with 1099 importing program using Turbotax online (on Chrome)
Apparently the program recognized my Banks/brokerage firms, in this case, it is Bank of America and Merrill Lynch. I say so because it asked for my password, asked me to check "I am not a robot", showed me a summary of items to be imported (together with the amount of each).
However, after the summary page, when the real import is supposed to start, the page just hangs. Basically the page shows a spinning loop for 10+ minutes until I got a warning about my session about to expire.
What's more: I tried to reload the import page a couple of times. It was a terrible idea -- now my income section is still correct but the tax owed amount just got multiplied many times.
This is terrible user experience. If I have another option, I'd be moving away from TurboTax
