I'm splitting my mortgage for my business in the Mortgage (home office) category, but it's not logging and being reflected on the expenses amount.

Hello there, Victor. Let me share some details about splitting transactions in QuickBooks Self-Employed (QBSE).

When assigning or splitting a transaction to the Mortgage home office category in QBSE, it will not reflect in your Profit & Loss and Tax Summary/Detail reports. To learn how Schedule C categories appear on reports, you can read this article: Schedule C and expense categories in QuickBooks Solopreneur and QBSE.

If you need to reflect those amounts as business expense, you'll have to choose other category. To ensure accuracy and compliance, I recommend consulting an accounting professional.

I'll keep an eye out for your reply. And if you have any other QBSE-related concerns, feel free to include them in the comments. We're here to assist you 24/7. Have a great day!
