yes, they must be covered with no adjustments.
But you can still aggregate the old way. I've been using TT since I guess sometime in the early 90s (I have 3 1/2 floppy install diskettes -yup guess I'm a hoarder) and only once did I actually do the download because of the volume.. So for decades I have used the other aggregating entries and yes there is a note about providing the originals. In the decades I've been doing it this way, the IRS has never once asked for those statements. And I think unlikely. A quick summing of my '23 1099s is about 90 pages from 3 brokerages.
