I had a problem importing from TD Ameritrade into H&R Block. I found the answer on the TD Ameritrade site in the instructions for Turbo Tax. May be the same issue. You do not use your normal internet login. You login with your account number and the password you use is actually the document ID for your 1099. It may be something similar with Wellstrade. From TD Ameritrade:
You will need the following information to import your TD Ameritrade tax data into tax preparation software:
Your 9-digit TD Ameritrade account number — To view your account number, go to Home > My Profile > Personal Information > Account information. Or, you can find your account number at the top of your Form 1099, which is located in the Tax Center under Your year-end tax documents.
Your 11-character document ID — To find your document ID, go to the top-right of your Form 1099.
Your 4-digit PIN — To edit your PIN, go to Home > My Profile > Personal Information > Account security.
For Gainskeeper®, enter [your 9-digit account number]@amtd for your UserID, and your 4-digit PIN as your password.
For TD Ameritrade, enter your 9-digit account number as your UserID, and your 10-digit document ID as the password. Include the dash when entering your document ID.
