Referencing Advice

Hi I am a new to both studying and HR. I’m a single mum and have started my level 3 CIPD qualification alongside part time working. I have completed my first assignment ( 9 questions - Business, culture and change in context). I need to go through my 9 questions now adding references - I know I probably should have done the references whilst doing the assignment and not all at the end but as I was struggling, didn’t recieve the tutorial support I had expected and put them off till now. I understand how I am supposed to reference and the type of references I need I am really struggling to find academic style references. I have lots of online newspaper, statistics, non reputable websites etc I am looking for models, theories, articles, book extracts etc. I have been looking so far on google and google scholar changing the date to ‘since 2021’ but I can’t seem to find the type of references I need. Does anyone have any tips where else I can look or how I can find acceptable and varied references please, Thank you Sophia
