It is basically the qualification for GS-13 grade, which requires at least one year of experience at the next lower level (GS-12). As you indicated, you have no record of Federal employment. Thus your answer MUST be No.
Most IT positions on the Federal line don't require a college degree, but it can be a plus when compete with others. The selecting officer mostly look on specific license, certificate, trainings...etc.
Again, good luck!
Dear, John.
You should definitely answer NO for this question since you do not have at least one (1) year of experience for the position at GS-12. It seems like you are applying for GS-13 grade. There might be other sections you can indicate your 10+ years of IT experience on the pre-formatted questions. Or on your own resume, you can express the significant positions, responsibilities, accomplishments...etc.
Good luck!
