We detected at least two customers that were processed, sent to the IRS, and accepted but there's no record on the homebase and we don't have their files on the data folder.

I searched the whole computer, checked the recycle bin, but there's no info from these customers. Like if they never been there. Both were transmitted successfully and accepted by the IRS but we lost all the information. I'm going to perform a backup of the home base just in case from now on but please let me know if you experienced the same issue.

We use Windows 10 home, version 20H2 Build 19042.1526

Thank you very much in advance for your help in regards to this matter.
