Thanks for posting in the Community, @Claudia11.

Allow me to chime in for a moment and help make sure that this is taken care of.

I agree with @Anonymous. The rebuild and verify data utilities are QuickBooks built-in diagnostic and repair tools that comb through, repair, and notify you of data damage within the file.

You can also check out this article for the detailed steps on how to run these tools: Resolve data damage on your company file.

That should help fix the error that you're getting. Please let me know how it goes by leaving a comment below. I'll be here if you need further assistance. Have a good one.
