This is for 2020 taxes. Looking at your date of March 2020 you must have been doing your 2019 taxes. This will not help you at this point---but if others are seeing something similar for 2020---it might.
I was also trying to import from Ameriprise. You need your Package ID (PID) and Document ID (DID) sent from Ameripise (it changes every year) or you can login into your account and look up your tax documents where the ecopy is. Anyway I was having a strange error whenever I typed in my PID and DID. It said that "1099 forms not yet available for tax year". I verified with Ameriprise that they were available. Apparently I figured out that I have two tax documents---one contained my 1099Div, INT, and had a PID and a DID and the other one was for my IRA 5498 form. The 5498 is not downloadable. Says right on the paperwork but I missed it. I switched to the PID and DID for the 1099 forms and it imported flawlessly. You have to make sure you type it in exactly as both the PID and DID are case sensitive. It solved my problem.
