Should be simple. How to set the Key Signature?

I can’t figure out how to set the key signature for my song. It in C and I can’t seem to do anything about it. I’m importing a midi file that isn’t in C and it’s resulting in all kinds of crazy notation!

Please help me by telling me how to set the key signature.

Thank You

Select the key symbol, click on the staff where you want the key signature.
