Hi @jessicavox,

I'll take care of this query about splitting transactions in QuickBooks Self-Employed (QBSE) for you.

If you're using a browser, it's an exclusive option to split transactions by percentage. Since you need to split transactions by amount, what you need to use is the mobile app for QBSE. 

Here's how:

1. Go to the Transactions menu.
2. Search for the transaction you want to split. 
3. Select Edit.
4. Choose the Split option.
5. Under the Category column, pick Personal or a business category for each split. 
6. Enter the exact amount for each split under the Amount column.
7. Press Add line if you need to add additional splits.
8. Hit Save when you're done.

See this article for more details about this process: Split transactions in QuickBooks Self-Employed. 

I'll share this article with you as well: Schedule C and expense categories in QuickBooks Self-Employed. It's a breakdown of Schedule C categories available in QBSE, along with their short descriptions.
