Get your taxes done using TurboTax

I had the same problem. Chatted with Schwab and they said they were working on it.  I saw different people were getting in but not consistent.  I tried again last night around 11:00 pm and got in and downloaded.  I believe the problem is with Schwab servers being over worked.  Try at off hours, early morning, late night. It worked for me. (windows ops)
