You can discover whether or not identity_insert is on, and if so for what table using the code below.

declare @tableWithIdentity varchar(max) = '';
SET IDENTITY_INSERT ExampleTable ON

begin try
  create table #identityCheck (id int identity(1,1))
  SET IDENTITY_INSERT #identityCheck ON
  drop table #identityCheck
end try
begin catch
  declare @msg varchar(max) = error_message()
  set @tableWithIdentity= @msg;
  set @tableWithIdentity = 
  SUBSTRING(@tableWithIdentity,charindex('''',@tableWithIdentity,1)+1, 10000)

  set @tableWithIdentity = SUBSTRING(@tableWithIdentity,1, charindex('''',@tableWithIdentity,1)-1)

  print @msg;
  drop table #identityCheck
end catch

if @tableWithIdentity<>''
begin
  print ('Name of table with Identity_Insert set to ON: ' + @tableWithIdentity)
end
else
begin
  print 'No table currently has Identity Insert Set to ON'
end
