Yes, unfortunately, you are correct. Your state might have different standards. Some states still allow the unreimbursed employee deduction. If you enter it in the Federal info, it will flow to your state.
Here is what the IRS says:
You are a qualified performing artist if you:
Performed services in the performing arts as an employee for at least two employers during the tax year,
Received from at least two of the employers wages of $200 or more per employer,
Had allowable business expenses attributable to the performing arts of more than 10% of gross income from the performing arts, and
Had adjusted gross income of $16,000 or less before deducting expenses as a performing artist.
