Weird disappearing tax return files

My 2024 TurboTax desktop finished tax return files have disappeared.  The original folder for 2024 is there but it is empty.  Even weirder - I booted up an older computer I had migrated from (Mac) and found the 2024 tax folder with the completed files - tt file backups and pdf of the finished return, but when I clicked on the pdf file, it poof! disappeared without a trace along with all of the other files in the folder.  I checked the recycle bin, hidden files in Finder, iCloud files, Dropbox - no luck. 

All I can figure is that the files I clicked on were automatically sent to a cloud destination which I have yet to find having looked at all the destinations.

Anyone who can shed some light - please step forward.  I've had to request a hard copy of the 2024 1040 form directly from the IRS, but after 3 months I am still waiting.  My tax preparer needs the info for the 2025 return coming up so I would love to find even just one copy of the finished return.

Again, this is on the TT Desktop not the Online version.
