How to enter cash transaction? My transaction tab always ask for a bank and I can't mannually enter transactions.

Hi there, 

Thanks for joining the Community. Dealing with missing transactions isn't the outcome I'd like for you to have. QuickBooks is designed to be an easy-to-use program and I'd like to help make sure you experience this benefit among others. 

The program allows you to manually upload transactions using a CSV. file. I encourage you to check out this article here as it shows you how to upload the transactions. In case you'd like to enter each individual transaction to a specific account, I recommend checking out the following article that shows you how to: Manually add transactions to accounts in QuickBooks Online.

Try this out and let me know how you make out. I'll be here to help.
