Hi there, Fernandezhk.

I'd like to share some solutions to help resolve your concern. If you still have the backup copy prior importing the inventory items, then you'll want to restore it. I've got this article for the instructions: Restore a backup of your company file.

Otherwise, you need to zero out the inventory shrinkage account by creating a journal entry. I'd recommend consulting with your accountant before doing the process. This is to ensure that your reports are accurate.

I'm also adding this article if you have other issues with inventory in QuickBooks Desktop: Fix negative inventory issues in QuickBooks Desktop.

If you need more help with QuickBooks Desktop, please let me know in the comments below. Take care!
