Hi there, @RBQSCKS. 

Thanks for taking the time to get back to us. 

As my colleague, Zack, mentioned above, once you've located the transaction that has the split, you can make any necessary edits to it. When a transaction is associated with more than one account, it will show as a split transaction in QuickBooks. 

Once the edit has been made to the transaction, it should no longer show the split. 

If you have further questions about this process, please let me know. Take care!
