The message you received - "Returns transmitted: - Federal Return, -Kansas Return"- indicates that both amended returns were e-filed.
If you needed to mail the amended KS return, the program prints out all the required federal attachments. It might seem like a lot of paper, but that is what the program has determined is necessary.
This might be more than in prior years, but KS filing requirement may have change this year and/or your federal return may be more complicated than in past years.
Sending more than is necessary is not a problem; sending less than is necessary could mean a delay.
