detailed investigation shortly after Trump left the White House and by May, 2021 had compiled a detail list of documents that needed to be returned, when they issued a formal request...so, it's been over 14 months since DJT was asked about the missing documents...also, it's clear that NARA has shown extreme deference to Trump due to his prior status as President...in spite of "Numerous" interactions with his attorneys...finally culminating in total frustration and the need for a "Search and Seizure" operation by the FBI...
There are lot more questions to be resolved before this is done...and many more people, other than DJT will end up being indicted...stay tuned...and up to date...but then, that's never been a priority of yours.
