Hey.
Have you had much guidance from your lecturers about the expectations of this lit review yet? Have they spoken to you about approaches to formulating a research question, gathering articles etc? Have you read many lit reviews (I found this was a great way to get my head around the process).
Usually they want you to show you can formulate a research question, search relevant databases sytematically and identify common themes or use data to answer your research question.
If you've got an idea of what you want to write about already, thats great. Start doing some informal searches of whats out there (I tend to use google scholar for this) to see whether there are specific areas within your topic of interest that you can find. This helps narrow your research question and see what literature there is out there to use. You may also find any key papers on the topic.
For structuring a formal search I tend to use the PICO method. This helps you to think about the search terms you want to use and structures the question you want answering. You should be searching more formal databases here, so CINAHL, MEDLINE etc. Theres a good explanation of what PICO is on this page by Exeter's libraries here:

Make use of your university library, they're expetis in searching for and sifting through information. It's likely they have tutorials on this topic that you can access. Speak to a librarian or lok online to see if there's anything on offer. They can usually get a hold of papers that you may not be able to instantly access through your uni as well.
