It's nice to see you here in the Community, Shauna. Let me provide information regarding your employment income and sole trader business for your taxes in QuickBooks Online (QBO).
QBO is designed to handle one business entity at a time. Combining your full-time employment income with your sole trader business isn't recommended, as it can complicate your record-keeping.
If you work as a contractor or are self-employed while also being a business owner, it's suggested that you use different products to track your income tax. QBO is best suited for your sole trader business, while QuickBooks Self-Employed (QBSE) is for employment earnings.
In addition, if you want to add your employment income to QBO, I recommend consulting with an accountant. They can guide you to classify and organize these transactions to maintain accurate records.
