Fed Interest/Dividends from SNVXX Government Money Market Fund (Schwab)

I have a 1099 DIV with $9101.37 in box 1a: Total Ordinary Dividends.  Of that amount $2143.54 came from SNVXX.  When I look up SNVXX, Schwab says at least 99.5% comes from US Government securities.  

After I enter the 1099 DIV in TTax, I am prompted with a series of check boxes.  One of them says: "A portion of these dividends is U.S. Government interest."  Since 99.5% or more of this fund is in government securities I checked the box.  I then entered $2,132.82, which is 99.5% of the total I received from SNVXX.

Did I handle this correctly?
