Import data from Charles Schwab problem
I was attempting to import all day. Getting error msg 590...useless...on phone with Schwab and TT. No answers there. Turbo tax said it was a problem "across" and they are working on it(I guess not too hard).
Fix that worked for me:
I noticed that in the Security section of Schwab there was an option to bypass verification on trusted devices. I have had difficulty understanding how that feature worked. On a whim, I checked the box that said verify on all devices.
Bingo...got a text with code from Schwab. Entered it and sure enough download started and import was successful. I hope this helps someone from spending days trying to figure it out!
