It sounds like you are trying to import the 1099s, and there is no import functionality with your issuer. However, you can import a pdf from your computer, or a quick way to do this is to manually import the 1099s.
Here is how to do this in TurboTax Online:
However...you should note that the SSA-1099sm does NOT go in with the regular 1099-R forms, there is a separate menu line for you to select to enter that information. The menu line indicates that it is for SSA-1099 and RRB-1099 forms
If you do not see the whole list of Income menu items...look for the text below what you have entered....to select a text line that says something like "See more Income items"....or something like that.
