I just tried a TurboTax import from Merrill Lynch at Noon Pacific time today Thursday 25 February 2021.
Progress!
I actually got to a logon screen for Merrill Lynch, for the very first time this week, with *no* "Maintenance Notification From Your Provider" error message from TurboTax, asking me to try again tomorrow.
At this point, I'll log in to Merrill and attempt an import.
