Whether you are an employee or an independent contractor depends on the working relationship between you and the employer.

If acting job #2 sent you a W-2, then they classified you as an employee, not a contractor. You report the W-2 as normal. It is considered separate and apart from your other work as an actor where you were treated as an independent contractor. You can't deduct any work-related expenses for acting job #2 on your schedule C.
If you want to contest the classification as an employee, you still have to file your 2023 tax return as if you were an employee. Then also file a form SS-8 to request an IRS determination. If the IRS issues a determination letter that you were an independent contractor, you will file an amended 2023 return to report your income and expenses from acting job #2 as self employment on schedule C, and remove the W-2 for acting job #2.
