Can I add transactions manually, I’m a real estate agent and my brokerage charges a transaction fee from my commission before handing me the check

Thanks for joining us here, @3sweetpeas1dream.

Yes, you can manually add a transaction in QuickBooks Self-Employed.

QuickBooks Self-Employed downloads your recent transactions automatically if you connect your bank and credit card accounts.
