A cache-related issue is likely causing the sidebar menu to be missing, nicendry.

When cache builds up, it can affect the performance of your browsing activities. Consider accessing QuickBooks through an incognito window or private browser to address this. This mode doesn't retain your browsing history, occasionally leading to software issues like encountering errors or missing options. You can use these shortcut keys as a reference:

• Ctrl + Shift + N  for Google Chrome
• Ctrl + Shift + P for Firefox
• Control + Option +P if you're using Safari

When it's now visible, return to the regular browser and clear the cache. This removes any historical data resulting in unusual browser behaviors. Switching to a different supported browser can also fix the issue.

In addition, you can assign categories to the transactions to ensure they are allocated correctly on the relevant line of your Schedule C: Categorize transactions in QuickBooks Self-Employed.
