After you file

Thank you!  Yes, that appeared to fix it and I was able to open the file after putting the file somewhere else on my hard drive.

 

One minor note for potential future reference, however: The real root of the issue appears NOT to be that OneDrive is being used but, rather, that the full TurboTax file needs to be present on the new PC first before trying to open it.  When Microsoft OneDrive is used on a new PC, all the files from your OneDrive cloud are not necessarily downloaded to the new PC.  There may initially only be file placeholders in your local OneDrive folder.  To get a file to be actually downloaded, you can do a couple different things, but one is to right-click on the file from File Explorer and select the OneDrive option "Always keep on this device", which forces the file to be downloaded immediately.  After I did this for other tax return files, I was able to open them with TurboTax without any issue.  In other words, the tax return files CAN reside in a OneDrive folder, but you must make sure the file has actually been downloaded locally first before trying to open the file in TurboTax.  Other applications such a Excel, Word, etc. do not have this problem and can gracefully interact with OneDrive to download files before opening them.  Apparently, TurboTax does not operate as gracefully and the user must intervene manually in this way.  This was my experience anyway

 

Thanks again.
