It may have somehow lost track of them, especially if they were on a USB-connected external drive. Always save them only on your system hard disk.
Use your file manager to find where the files are stored...then start up your TTX sofware and use the upper left corner...
<File
<<Open tax return
to browse to each file...and open and save it one more time...then repeat for each file in whatever directory it is located in. then the path to those files is re-established.

Btu again..only save them on the system hard disk. Storing them on a cloud drive ( One Drive ), or on a connected memory device is problematic. Those other types of storage are only for 2nd copy backups.
