Hi there.
Welcome tot he Community. QuickBooks is deigned to help get your work. I'll be happy to help so you can continue to experience the benefits offered in the program.
I can see the benefit of being able to enter a more than 1840 journal entries. While the function to have more than the specified number is unavailable due to usage limits, I recommend sending feedback about this to our engineers. Let me know if this info helps and if you have questions, don't hesitate to ask in the comments below.
I'm here to help!
