I made an investment in a commercial theatrical project. How do I categorize that expense in Quickbooks Self Employed?

Hello there, equilateral. 

All our categories feed into broad IRS Schedule C categories. If we can't look for any specific expense category, we can select whichever category makes the most sense to you and we'll make sure your expenses go where they affect in Schedule C.

You can check out these categories for more details and what are the included subcategories under them: Categories in QuickBooks Self-Employed. To categorize a transaction, just click on the right most arrow of the transactions and click the Type and then Category. Click Save to update the transaction's information. 

Feel free to get back to me if you need more help. Take care!
