Unlike a dissertation research question, this question has to be answerable without collecting original data.
You should be able to answer it based only on a review of existing publications. Start by creating a list of keywords related to your research topic. You can add to this list if you discover new keywords in the process of your literature search. Use your keywords to begin searching for sources.

There's certainly nothing wrong with citing information from a PhD thesis if it's relevant to your chosen topic. Feel free to do so. Hi Shona I just wanted to say that this is an absolute lifesaver and I feel so much more confident about writing my literature review for my research proposal after reading this- I was in a complete mess before! Thank you so so much for writing this! My literature is divided in 5 sections: Introduction, methodology, findings discussion and conclusion.
Where do I show the gap in literature. Is it in my findings section or discussion section.

I have written my proposal for my MA and about to start my thesis write up. where do I start and can I use my proposal or do I need to start from scratch?

Check with your supervisor whether you're allowed to copy passages of text directly from your proposal or if it needs to be rewritten; if you submitted the proposal as an assignment for credit, re-using it may be considered self-plagiarismbut universities have different rules about this.
A good literature review doesn't just summarise individual sources in turn, but synthesises them — that means that each paragraph should connect the findings of a few related sources rather than just summarising a single source. This article about synthesising literature can help you get started.
I was wondering if it is allowed to use the abstract from a paper to use as a summary for the literature review? No, you should never copy the text of an abstract into your literature review; try to summarise the study in your own words. If you want to get a quick overview of a study's main findings, the abstract is a good place to start. But it's always best to read the full paper if possible or, at the very least, read the introduction and conclusion before including it in your literature review, how to structure a scientific literature review.
If you want to use a sentence or short passage from the paper, make sure to properly quote — but paraphrasing is usually a better choice, as it shows you've read and understood the paper. Remember that the literature review isn't just a list of summaries, but an original text that explains and draws connections between existing research.
