Hi Amanda,
Thanks for asking for help. Here's a couple of tips.
The citations for your sources can be listed under the Sources section but should be just the citation itself. Like the one for Find a Grave that you have added (the info after the word citation).
If you want to include the other details, put them in a Research Notes section or another section of the biography like === Death ===
The Research Notes section has the two equal signs == while biography subsections have three equal signs ===
If you want to start a new line use a colon at the very beginning of the line :
If this is a little confusing, let me know and I can add some of these details so you can see what I mean.
Hope that helps.
Edited for clarity
