How to interpret TD-DFT results for finding λmax and amplitude
You are looking at the wrong numbers.

You should look for excitation  that has non-zero oscillator strength. In the text file "State # 1,2 .." and in Chemissian on the left, list with columns "# Energy Strength" The transitions with zero or very small oscillator strength has a very low intensity in the spectrum, so you don't see them. 
In your case the relevant excitation are #2 (Energy: 6.691 eV, Strength: 0.027) and #4 (Energy: 8.353 eV, Strength: 0.042), and you can see them as small peaks on the graph down.

The "amplitude .. 1.41" has nothing to do with the oscillator strength. It tells you which orbital contributions are the most important ones for the given excitation.
