Hi Carly881,
Thank you for your post, and welcome to the Community Forum.
I understand that you've accidentally exported and processed the wrong ABA file for your last pay run. This can indeed cause issues when trying to reconcile as the transaction amount doesn't match the electronic payment. To rectify this, you may need to delete the incorrect electronic payment and recreate the correct one. For more information, please refer to this Help article: Changing or fixing electronic payments.
Feel free to create a new post again if you need further assistance.
