I'm just curious if like, for example I was trying to answer a story-id question, am I allowed to use other q and a cites to find an answer to the question I'm trying to answer.

So as long as you're not just word-for-word copy-pasting questions to somewhere else, that's fine.
Aside from that, it's perfectly acceptable and even encouraged to use other sites as sources. Just keep in mind the guidelines for referencing, and you should be fine with getting an answer elsewhere and then using that as a source for an answer here. Make sure that you're not just reposting what they wrote here; elaborate, explain more, add sources, include your own work...
As an aside - linking people here from other sites, especially if they could answer a question, is a great way to drive traffic, and you can even win badges for driving people here using the "share" link on the bottom of every post (in the format
https://literature.stackexchange.com/[a or q]/[post id][your user id]). Just make sure that the people you're driving here are at least nominally aware of how the site is different from standard internet forums - linking them to the tour or How to Answer can save a lot of time and aggravation on both ends.
