Thanks so much. Going forward I will uncheck all boxes authorizing electronic payments. Fortunately, my client had funds available to cover the duplicate withdrawals.

I thought e-filing amended returns would make the process easier, but nothing could be further from the truth.

Thanks for the information on cancelling quarters 3 and 4 payments. The number for cancelling electronic payments is also on the 9325.

I think the whole amended return process in ProSeries needs a revamp to improve clarity, but I don't think I will ever see it. It is way too confusing. 

Thanks again for your input. Much appreciated.
