K-3 info

Received a K-1 with box 16 checked, stating there is a k-3 attached.  However, confirmed with the support staff that the K-3 for 2021 will not be issued until late Aug 2021.  Since the box 16 is checked, turbo tax requests to add info from k-3,  those blocks are in error, but I have no idea what they should be.  Please advise.
