Hi m_elias1,
Welcome to Community! QuickBooks is a dynamic program to complete your daily accounting tasks with peace of mind. It's important that you're able to successfully record the deposit to your shareholder loan. I'll be happy to help!
To record the loan accurately, you'll need to create a liability account and enter a journal entry. Follow this link to see the complete guide to record this type of entry in QuickBooks Desktop.
If you have any other questions, please don't hesitate to reach out. We'd be glad to assist!
