Here are 3 from my resource collections:

Assess your tech skills (https://survey.fgcu.edu/Survey.aspx?s=311d40c08e234f9181d7f97e6623fbcc)

Self-assessment of tech skills (http://wikieducator.org/Technology_Self-Assessment_Questionnaire)

Survey about your tech use (https://www.quia.com/sv/55395.html)

Hope one of those works!
