hi,
In "Advanced filters" , click "add filters", select "Incident ID" then select the operator 'Is any of" (or "Is none of") and add list of ID you wanna see (or dont wanna see) in your report then click on "Apply".
For archived incident it depends if you are talking of "web archive" or incident tagged as archive in DLP tool. For the firt one you cant as web archive is a static view. For second one, in order to view them you must have a profile which has right to view archived incident then select "is archived" as filter and set correct value (see only archived incident or all).
One things that you have to take care of is that in all reports you have two filters, one on "status" and one on "date" so be sure that these ones are correct too.
Once you have set a report and you are happy with it, you can "save it" (be sure to first click on apply as "save" take only into account filters already applied).
For more information, i think you should have a look at admin guide of your DLP version.
Regards.
