Narrative:

Misread crossing altitude at jawbn intersection. Used turboprop altitude vice turbojet altitude. After reviewing several arrival plates, we found that the turboprop altitude was always under the turbojet altitude on the intxns with altitude restrs. On the seattle 20-2C plate, the turboprop altitude is on top of the turbojet altitude at jawbn intersection.
