When I import the accounts, TurboTax puts them all together under the name of the brokerage. I want to separate them: interest and dividents from my XYZ account, and interest and dividends from my wife's XYZ account.
The only way to do what you want would be to manually enter one spouse's broker and dividends.
Then, for example, say you both used Charles Schwab, for her account (if that is one manually entered) you would call it Charles Schwab-S (for spouse).
If you both have stock transactions and do imports on both, just delete the interest and dividends and this will easier to reinput only these.
Multiple Brokerage Accounts
If you have a single broker for multiple accounts, when the selecting to add another account for the same broker: Clear cookies and then search for your broker via the search bar rather than clicking the broker icon. This should allow the screen to input account information and import the data.
Such an awesome work around. Don't click the icon and search it, it works!! Thanks a lot.
At least for Schwab, one do this in Step-by-Step by selecting the desired accounts via the checkboxes in the broker's interface page, do the imports, then go to Forms and then add an identifying suffix to the form name. But caution! if you go back to Step-by-Step and import again, Turbotax seems to delete the already-imported forms even if you have renamed them.
