You don't file a schedule C.  If you are a member in a multi-member LLC, the LLC prepares a 1065 partnership return and issues a K-1 to each partner.  

as part owner of LLC

That part of your statement indicates you have a multi-member LLC. For an LLC with more than one owner, you do not and can not use SCH C. All business income/expenses are reported on an 1065-Partnership/Multi-member LLC tax return. The business will then issue each owner a K-1. Each owner will need that K-1 in order to complete their personal 1040 tax return.

The 1065 partnership return is due by March 15th - one month before the personal 1040 tax return deadline. All K-1's must be issued by March 15th also.

To complete the 1065 return, you will need TurboTax Business.  https://turbotax.intuit.com/small-business-taxes/

The money you invested in the partnership becomes your basis in the partnership ... the income and expenses are reported on the partnership return and are passed thru to you on the K-1 form ... do NOT also file a Sch C as that is not correct. 

Thank you very much for contributing

This makes sense and is very helpful. Thank you.

It seems there are possibly 2 things I need to consider: Section 181 and 168A.  Are you familiar with either one of these re: film deductions?

@DEBTT Code 181 allows an investor in a qualified film or television or live theatrical production to expense the purchases of equipment and other items which would normally be required to be depreciated over a number of years. Thus, you may be able to accelerate the deduction of major purchases. In general, the production must have a budget of under $15,000,000 and the production must be done in the United States. Here is more on the section  Section 181

Section 168(a) applies to accelerated depreciation, wherein you are allowed to deduct more in the early useful life of an asset than you would under straight line depreciation, where you take an even deduction each year. Here is more on section 168(a)  Section 168(a)
