Ending a financial year

Hi All, still learning this program and began halfway through this last financial year. So I have just been using it as a way or recording my purchases and receipts without having an opening bank balance. Now I want to end the financial year and be able to give these totals to the business doing my tax and I didn’t enter an opening bank balance and haven’t inputted personal drawings etc. I can’t seem to find how to end this last year so I can begin the next, so the last years totals don’t appear on the new year. I have not been doing a reconciliation at the end of month and it isn’t going to match my bank accounts anyway. I don’t need this program to run as a full account program just. Feeling a little lost.
