Investors & landlords

I'm having the same problem...all weekend, March 4,5 and 6, 2021.  Try to download by log in to Intuit fine, enter login for Schwab account fine and within 10 seconds of entering, get the reply "! Login is temporarily unavailable. Please try again later or call customer support."  I have tried probably a dozen times each on Fri, Sat and Sunday with the same results.  I also changed my password with Schwab and verified no TTax updates are needed in my CD copy of TTax 2021.  Obviously the issue is still with us.  I'm on a Windows 11 PC and have used TTax Premier and the download of 1099's for  some 11 years now...and this is the first time I've had such a problem.  Hope Intuit works this bug out ASAP!
