So many options for you to go forward.
When I knew nothing about DNA when I tested, I watched as may DNA videos as possible (I do not learn easily via video). What helped me most were the ones at [https://familytreewebinars.com/] some free, but most you have to pay for. Then the youtube channels Genealogy TV and Family History Fanatics.
Now I quite know a bit more. The main thing that these sites repeat over and over is that traditional research is the key to getting the best leverage from DNA results.
So not easy, and you invariably WADE THROUGH THE MATCHES and hopefully find answers.
There are tools ans sites that help, putting your results on other sites also helps MyHeritage and Gedmatch (free), FTDNA for a small fee, which widens the net for matches.
There are also tools that can help such as DNA Painter. It can all be a bit hard to take in how to use, which I have not mastered as yet.
Even then, I still have a few brick walls and more mysteries, for example my husband (Australian), seems to have many matches to Kuykendall and Bolling in South Carolina and I can not find ANY connection to the USA and the many Matches - there is a link somewhere... where?????
So I would pick on your closest match that has a tree, and stick to looking at the shared matches, which hopefully, will help you find the "generation of connection" and how you fit in the tree.
