I made the same mistake. Putting April 2024 for one of the months and them May 2023 but the most unusual thing is that QB still let me reconcile the month of May 2023 with the correct year 2023 so I have one month April in the future in my reports May in the past. It does not make sense how QB would record this, and the balance is still not off. I am positive that it's a bug in their program that needs to be fixed as it is messing up the books for a lot of us. I don't have an accountant so I should be given access to fix my own books if it's just a simple date error.
First of all, the system should have caught the error and not let me reconcile the next month if the dates were off but seems like it failed to do this so the only other thing, I can think of is a BUG in the program that's needs to be fixed ASAP.
I am really frustrated, and I realized that it a common mistake that a lot of people made, and their generic answer is not solving the problem for anyone.
