Is there a way to enter your deposits and credit for a previous year?

Thank you for posting here in the Community, shereensimon11 .

It depends if you haven't closed your books for the previous year. Then, you can enter a normal bank deposit and credit and set the date to the last year.

I'd suggest consulting your accountant to determine the correct posting and for proper guidance.
