I received an error message that I have never seen before.  2021 Electronic Pre-Transmission Error Report  Exception occurred during EF batching Client: 112233

An item with the same key has already been added.

at System.ThrowHelper.ThrowArgument Exception (ExceptionResource resource) at System.Collections.Generic.Dictionary'2.Insert(TKey key, TValue, Boolean add)

at System.Collections.Generic.Dictionary'2.System.Collections.Dictionary.Add (Object key, Object value)

at Intuit.Efile.Implementation.EFBatchSubmit.DoExecute (IEFClientSubmitInfosubmitInfo)

at Intuit.EFile.Implementation.EFBatchSubmit.Execute (IEFClientSumitInfosubmitinfo)

What does this mean and what do I need to do?
