Thank you, worked for me as well!

Awesome, it worked! THANK YOU SO MUCH.

You CAN import all your tax information into TurboTax from Stash. Review the tax documents provided by Stash. The easiest way to do this is through the Stash app under Settings>Statements and Documents>Tax Documents. Copy or screenshot your account number and type of tax document (is: 1099-DIV, 1099-B, etc...) at the top of pg. 1. In TurboTax, select the financial section that corresponds to your 1099 type. After two self explanatory questions, you’ll be asked to enter your financial institute into the

search field. Type “Apex” and select Apex Clearing. Under  Apex Username type 10- and the Stash account number located at the top of your 1099  proved by Stash. The Password will be your SS#.

If unsuccessful, you’ve likely selected the incorrect entry screen.   Don’t get frustrated, I failed multiple times until realizing TurboTax has various tabs  where  importing is possible. If unsuccessful after multiple attempts, enter your 1099 “type” in the search field and TurboTax will direct you to the appropriate section.    

Perfect, it worked..thanks man. Putting 10- before stash user account. Who would tell that.. Stash should, but didn't!!!.

worked for me too. many thanks 

This does not appear to work. I have tried the account number with and without the 10- and also the SS# with and without dashes......none of them work. Have they made changes for this year? I am amazed that Stash does not provide any communication on this topic. It makes me want to dump them altogether.
