I work as a registered nurse. Where do I put in expenses paid for uniforms.?

Unfortunately, Employee Business Expenses were eliminated with TCJA. They are no longer deductible.

Is renewing nursing license deductible? I’m confused on what if any expenses can be deducted as a nurse if work related expenses have been eliminated

All unreimbursed employee expenses have been eliminated, so unfortunately there is nothing that can be deducted.

The above answers apply if you are a W-2 employee.  However, if you work as an independent contractor (your income is reported to you on a 1099-MISC instead of a W-2), the expenses you mention would be reported as a business expense on Schedule C.
