Happy to help, @SD441.

I'll go over some troubleshooting procedures to help you resolve the QuickBooks Self-Employed (QBSE) can't tag deposit issue.

When attempting to tag the deposit transaction in your QBSE, did you receive any errors? If so, could you please describe the error in detail? By doing so, I can examine the problem in more detail and offer a precise solution to help fix the issue.

In the meantime, I'd recommend logging into your account through incognito. This way, we can check if it's a browser-related issue. Sometimes, too much cache build-up in your regular browser can cause unexpected behavior in the product. 

Refer to the keyboard shortcuts below:

• Ctrl + Shift + N (Google Chrome)
• Ctrl + Shift + P (Firefox)
•  Control + Option + P (Safari)
•  Ctrl + Shift + P (Microsoft Edge)

Once in, tag the deposit again to verify if it's performing well. If it's solved, return to your regular browser and press the CTRL+ Shift and Delete keys on the keyboard to clear the cache.

Feel free to read through the articles below to on how to add transactions manually and learn more about Schedule C in QBSE:

You're always welcome to reply to this thread if you have a follow-up question or other QuickBooks concerns. I'll never get tired of helping you. Keep safe. 

Spoke with quickbooks, this is still an issues and they have been working to fix the problem.

however it’s been over 3 months with the problem.

 It’s  only a problem on a Mac laptops and not Apple laptops. 
I did ask if they had a desk top version for self employed but unfortunately that’s not available.

hope this is solved soon as the end of the year reports are coming soon.
