The point is that my financial institutions provided a composite tax document for each account held at the respective firms. When I imported that composite tax document, Turbotax failed to import a single type of transaction across multiple accounts.
Upon completing the forms, I reviewed the outcome only to confirm that a file was uploaded for each account, I didn't have any reason to believe that some things would be imported on an account while others were not.
I went back to the tax documents at both Schwab and EJ and confirmed, there is only one document per tax year per account.
I also used Turbotax for 2020, and had the same variables (one tax document, multiple taxable transactions, multiple accounts at multiple institutions), and all of the details appear to have been imported correctly.
It just doesn't make sense.
