A am a teacher with a number of classroom/lab expenses, but I teach at a community college not k-12

[Clemkat]

Are my supplies deductible?

You might be able to enter job-related expenses but you are not eligible for the educator credit for K-12 teachers.

Only the amount of job-related expenses that are OVER 2% of your adjusted gross income get added to your list of itemized deductions, which still must exceed your standard deduction in order to make a difference on your return.  This is kind of a hard deduction to get.  If you need to enter these, go to Federal>Deductions and Credits>Employment Expenses>Job-Related Expenses.
